The structure of bis(1,10‐phenanthroline‐κ2N,N′)(thio­sulfato‐κ2O:S)­manganese(II) methanol solvate, [Mn(S2O3)(C12H8N2)2]·CH3OH, is made up of Mn2+ centers coordinated to two bidentate phenanthroline (phen) groups and an S,O‐chelating thio­sulfate anion, forming monomeric entities. The structure of catena‐poly­[[di­aqua(2,9‐di­methyl‐1,10‐phen­anthro­line‐κ2N,N′)­manganese(II)]‐μ‐thio­sulfato‐κ2O:S], [Mn(S2O3)(C14H12N2)(H2O)2]n, is polymeric, consisting of Mn(dmph)(H2O)2 units (dmph is 2,9‐di­methyl‐1,10‐phenanthroline) linked by thio­sulfate anions acting in an S,O‐chelating manner.  相似文献

catena‐Poly[[[tetra­aqua­zinc(II)]‐μ‐4,4′‐bipyridine‐κ2N:N′] [[μ‐thio­sulfato‐κ2O:S‐bis­[(thio­sulfato‐κS)zinc(II)]]‐di‐μ‐4,4′‐pyridine‐κ4N:N′] dihydrate], {[Zn(C10H8N2)(H2O)4][Zn2(S2O3)3(C10H8N2)2]·2H2O}n, is a polymeric zinc complex built up from thio­sulfate‐containing anionic chains, where the Zn atom is tetra­hedrally coordinated, and aqua‐containing cationic chains incorporating octa­hedrally coordinated Zn. In each type of chain, the 4,4′‐bipyridine units act as spacers, and the chains run along three non‐inter­secting almost orthogonal directions in space. The profusion of hydrogen‐bond donors (all the H atoms of the water mol­ecules) and acceptors (the thio­sulfate O and S atoms) generates a very complex hydrogen‐bonding scheme.  相似文献

The title polymeric compound, catena‐poly­[dipotassium [bis­[μ‐N‐salicyl­idene‐β‐alaninato(2−)]‐κ4O,N,O′:O′′;κ4O′′:O,N,O′‐dicopper(II)]‐di‐μ‐iso­thio­cyanato‐κ2N:S2S:N], {K[Cu(NCS)(C10H9NO3)]}n, consists of [iso­thio­cyanato(N‐salicyl­idene‐β‐alaninato)copper(II)] anions connected through the two three‐atom thio­cyanate (μ‐NCS) and the two anti,anti‐μ‐­carboxyl­ate bridges into infinite one‐dimensional polymeric anions, with coulombically interacting K+ counter‐ions with coordination number 7 constrained between the chains. The CuII atoms adopt a distorted tetragonal–bipyramidal coordination, with three donor atoms of the tridentate Schiff base and one N atom of the bridging μ‐NCS ligand in the basal plane. The first axial position is occupied by a thio­cyanate S atom of a symmetry‐related μ‐NCS ligand at an apical distance of 2.9770 (8) Å, and the second position is occupied by an O atom of a bridging carboxyl­ate group from an adjacent coordination unit at a distance of 2.639 (2) Å.  相似文献

In the title compound, catena‐poly­[[bis­(aniline‐N)cadmium(II)]‐di‐μ‐thio­cyanato‐S:N;N:S], [Cd­(SCN)2­(C6H7N)2], the CdII atom lies on an inversion centre and is in a distorted octahedral geometry. The coordination sphere contains two thio­cyanate (SCN) S atoms, two iso­thio­cyanate (NCS) N atoms and two aniline N atoms. The six‐coordinated Cd atoms run parallel to the b axis and are doubly bridged with neighbouring Cd atoms by SCN and NCS ligands. Thus, this complex has a one‐dimensional coordination polymeric chain structure in which the aniline ligand is in the trans conformation.  相似文献

The title compound, dicaesium(I)‐μ‐thio­cyanato‐κ2N:S‐zinc(II)‐tetra‐μ‐thio­cyanato‐κ2S:N‐argentate(I), crystallizes in the orthorhombic space group Pmn21 and contains units of composition AgZn(SCN)3 lying on a mirror plane and bonded together through Cs+ ions and thio­cyanate groups. The crystal studied contained equal numbers of inversion twins.  相似文献

The title compound, [Cd(S2O3)(C16H16N2)(H2O)]n, presents a polymeric one‐dimensional structure running along the P21/c glide direction, with elementary units defined by six‐coordinate CdII atoms bonded to three symmetry‐related thio­sulfate groups, a bidentate tetra­methyl­phenanthroline ligand and one aqua ligand. The bridging thio­sulfates bind metal centers through two different sequences, viz. Cd—S—Cd′ and Cd′—S′—S′—O′—Cd, defining a closed six‐membered ring. Individual chains are held together viaπ–π inter­actions to generate two‐dimensional networks parallel to the (100) plane. These, in turn, are connected by much weaker van der Waals inter­actions.  相似文献

Bis(N,N‐di‐n‐butyl­di­thio­carbamato‐κ2S,S′)(1,10‐phenanthroline‐κ2N,N′)­zinc(II) ethanol hemisolvate, [Zn(C9H18NS2)2(C12H8N2)]·0.5C2H6O, (I), and bis(N,N‐di‐n‐hexyldithiocarbamato‐κ2S,S′)­bis(1,10‐phenanthroline‐κ2N,N′)calcium(II), [Ca(C13H26NS2)2(C12H8N2)2], (II), are mixed‐ligand com­plexes. In the first compound, the Zn atom has a distorted octahedral coordination, while in the second compound, the Ca atom is eight‐coordinate, with four S and four N atoms forming a highly distorted cube.  相似文献

In the novel title six‐coordinate cadmium complex, [Cd(S2O3)(C12H8N2)]n, the anion binds to three different six‐coordinate cationic centres through all four external atoms, an unprecedented coordination mode for thio­sulfate metal‐organic complexes. This connectivity leads to strongly linked dimers, connected to form interleaved double chains, which in turn interact through remarkably short π–π bonds between their phenanthroline groups.  相似文献

The title compound, [Dy2(C8H7O2)6(C12H8N2)2], forms binuclear complexes, viz. di‐μ‐4‐methyl­benzoato‐κ4O:O′‐bis[bis(4‐methyl­benzoato‐κ2O,O′)(1,10‐phenanthroline‐κ2N,N′)dyspros­ium(III)] tetra‐μ‐4‐methyl­benzoato‐κ8O:O′‐bis[(4‐methyl­benzoato‐κ2O,O′)(1,10‐phenanthroline‐κ2N,N′)dyspros­ium(III)]. There are two independent binuclear com­plexes in the asymmetric unit, both of which are centrosymmetric. In one, the DyIII ions are linked by two bridging 4‐­methyl­benzoate groups, while in the other, the DyIII ions are linked by four bridging 4‐methyl­benzoate groups. The remaining 4‐methyl­benzoate groups and 1,10‐phenanthroline units coordinate to just one metal ion in bidentate modes.  相似文献

The title cadmium(II) polymer, catena‐poly[[[bis­(4‐amino­pyridine‐κN)­aqua­cadmium(II)]‐μ‐1,4‐phenyl­enediacetato‐κ4O,O′:O′′,O′′′] dihydrate], {[Cd(C10H8O4)(C5H6N2)2(H2O)]·2H2O}n, comprises one‐dimensional wave‐like chains, in which the Cd atom is coordinated by 1,4‐phenyl­enediacetate and 4‐amino­pyridine molecules. The 1,4‐phenylenediacetate ligands lie about inversion centres. Extensive hydrogen‐bonding inter­actions between the chains lead to a three‐dimensional structure. Free water mol­ecules form chains in the structure.  相似文献

In the title complex, poly[cadmium(II)‐μ2‐1,4‐bis­(1,2,4‐triazol‐1‐ylmeth­yl)benzene‐di‐μ2‐thio­cyanato], [Cd(NCS)2(C12H12N6)]n, the CdII atom lies on an inversion centre in a distorted octa­hedral environment. Four N atoms from the thio­cyanate and 1,4‐bis­(1,2,4‐triazol‐1‐ylmeth­yl)benzene (bbtz) ligands occupy the equatorial positions, and two S atoms from symmetry‐related thio­cyanate ligands occupy the axial positions. The benzene ring of the bbtz ligand lies about an inversion centre. Single thio­cyanate bridges link the CdII atoms into two‐dimensional sheets containing novel 16‐membered [Cd4(μ‐NCS‐N:S)4] rings. The bbtz ligands further link these two‐dimensional sheets into an unprecedented covalent three‐dimensional network for the cadmium–thio­cyanate system.  相似文献

catena‐Poly[[aquabis(nitrato‐κ2O,O′)cadmium(II)]‐μ‐1,2,3,6,7,8‐hexa­hydro­cinnolino[5,4,3‐cde]cinnoline‐κN1N6], [Cd(NO3)2(C12H12N4)(H2O)]n, (I), and catena‐poly[[[bis(nitrato‐κ2O,O′)cadmium(II)]‐μ‐2,2,7,7‐tetra­methyl‐1,2,3,6,7,8‐hexahydro­cinnolino[5,4,3‐cde]cinnoline‐κN1N6] chloro­form solvate], {[Cd(NO3)2(C12H12N4)]·CHCl3}n, (II), are the first structurally examined cadmium–pyridazine coordination compounds. They possess one‐dimensional polymeric structures supported by the bidentate bridging function of the cinnolino[5,4,3‐cde]cinnoline ligands, which lie about inversion centres. The Cd atoms are seven‐coordinated in (I) and six‐coordinated in (II), involving two bidentate nitrate groups [Cd—O = 2.229 (2)–2.657 (2) Å], two N atoms of the cinnoline ligands [Cd—N = 2.252 (2)–2.425 (2) Å], and, additionally, a water O atom in (I) [Cd—O = 2.284 (2) Å]. In (I), the coordinated organic and aqua ligands form an intra­molecular O—H⋯N hydrogen bond [O⋯N = 2.730 (3) Å].  相似文献

The title complex, chloro­bis{ethyl N‐[(4‐methyl­anilino)­thio­carbonyl]­carbamate‐κS}copper(I), [CuCl(C11H14N2O2S)2], was synthesized by the reaction of cupric chloride with the corresponding thio­urea derivative. The complex has imposed crystallographic m symmetry and the CuI coordination environment is trigonal planar, formed by two S atoms and one Cl atom. The formation of intramolecular hydrogen bonds promotes the stability of the complex.  相似文献

The crystal structures of two complexes containing the peroxodisulfate anion are reported, namely μ‐peroxodisulf­ato‐1κO:2κO′‐bis­[(acetato‐κ2O,O′)aqua­(2,2′:6′,2′′‐terpyridine‐κ3N,N′,N′′)cadmium(II)] hepta­hydrate, [Cd2(C2H3O2)2(S2O8)(C15H11N2)2(H2O)2]·7H2O, (I), and catena‐poly[[[bis(2,2′‐bipy­ridine‐κ2N,N′)mercury(II)]‐μ‐peroxodisulfato‐κ2O:O′] 0.4‐hy­drate], {[Hg(C10H8N2)2(S2O8)]·0.4H2O}n, (II). In both structures, the anion behaves as a bridge, linking neighbouring coordination polyhedra in two different ways, either tightly bound to the hepta­coordinated Cd2+ cation forming neatly separated dimeric entities in (I) or across a shorter O—S—O path producing weakly connected chains by way of `semi­coordination' to the Hg2+ cations in (II).  相似文献

Two differently hydrated crystal forms of the title compound, viz. bis­(acetato‐κ2O,O′)(2,9‐di­methyl‐1,10‐phenanthroline‐κ2N,N′)­mercury(II), [Hg(C2H3O2)2(C14H12N2)] or [HgAc2(dmph)] [dmph is 2,3‐di­methyl‐1,10‐phenantroline (neocuproine) and Ac is acetate], (I), and tris­[bis­(acetato‐κ2O,O′)(2,9‐di­methyl‐1,10‐phenanthroline‐κ2N,N′)­mercury(II)] hexadecahydrate, [Hg(C2H3O2)2(C14H12N2)]3·16H2O or [HgAc2(dmph)]3·16H2O, (II), are presented. Both structures are composed of very simple monomeric units, which act as the building blocks of complex packing schemes stabilized by a diversity of π–π and hydrogen‐bonding interactions.  相似文献

A new cadmium–thiocyanate complex, namely catena‐poly[1‐carboxymethyl‐4‐(dimethylamino)pyridinium [cadmium(II)‐tri‐μ‐thiocyanato‐κ4N:S2S:N] [[[4‐(dimethylamino)pyridinium‐1‐acetate‐κ2O,O′]cadmium(II)]‐di‐μ‐thiocyanato‐κ2N:S2S:N]], {(C9H13N2O2)[Cd(NCS)3][Cd(NCS)2(C9H12N2O2)]}n, was synthesized by the reaction of 4‐(dimethylamino)pyridinium‐1‐acetate, cadmium nitrate tetrahydrate and potassium thiocyanide in aqueous solution. In the crystal structure, two types of CdII atoms are observed in distorted octahedral coordination environments. One type of CdII atom is coordinated by two O atoms from the carboxylate group of the 4‐(dimethylamino)pyridinium‐1‐acetate ligand and by two N atoms and two S atoms from four different thiocyanate ligands, while the second type of CdII atom is coordinated by three N atoms and three S atoms from six different thiocyanate ligands. Neighbouring CdII atoms are linked by thiocyanate bridges to form a one‐dimensional zigzag chain and a one‐dimensional coordination polymer. Hydrogen‐bond interactions are involved in the formation of the supramolecular network.  相似文献

The structures of two new sulfate complexes are reported, namely di‐μ‐sulfato‐κ3O,O′:O′′‐bis{aqua­[2,4,6‐tris(2‐pyridyl)‐1,3,5‐triazine‐κ3N1,N2,N6]­cadmium(II)} tetra­hydrate, [Cd2(SO4)2(C16H12N6)2(H2O)2]·4H2O, and di‐μ‐sulfato‐κ2O:O′‐bis­[(2,2′:6′,2′′‐ter­pyridine‐κ3N1,N1′,N1′′)­zinc(II)] dihydrate, [Cd2(SO4)2(C15H11N3)2]·2H2O, the former being the first report of a Cd(tpt) complex [tpt is 2,4,6‐tris(2‐pyridyl)‐1,3,5‐triazine]. Both compounds crystallize in the space group P and form centrosymmetric dimeric structures. In the cadmium complex, the metal center is heptacoordinated in the form of a pentagonal bipyramid, while in the zinc complex, the metal ion is in a fivefold environment, the coordination geometry being intermediate between square pyramidal and trigonal bipyramidal. Packing of the dimers leads to the formation of planar structures strongly linked by hydrogen bonding.  相似文献

In poly[[μ3‐2,2′‐(disulfanediyl)dibenzoato‐κ5O:O,O′:O′′,O′′′](1,10‐phenanthroline‐κ2N,N′)cadmium(II)], [Cd(C14H8O4S2)(C12H8N2)]n, the asymmetric unit contains one CdII cation, one 2,2′‐(disulfanediyl)dibenzoate anion (denoted dtdb2−) and one 1,10‐phenanthroline ligand (denoted phen). Each CdII centre is seven‐coordinated by five O atoms of bridging/chelating carboxylate groups from three dtdb2− ligands and by two N atoms from one phen ligand, forming a distorted pentagonal–bipyramidal geometry. The CdII cations are bridged by dtdb2− anions to give a two‐dimensional (4,4) layer. The layers are stacked to generate a three‐dimensional supramolecular architecture via a combination of aromatic C—H...π and π–π interactions. The thermogravimetric and luminescence properties of this compound were also investigated.  相似文献

The title compound, [di­acetyl­pyridine bis(S‐methyl­iso­thio­semicarbazonato)]­iodo­nickel(II), [Ni(C13H18N7S2)I], is the first example of a complex involving the 2N coordination of the iso­thio­semicarbazide moiety. 2,6‐Di­acetyl­pyridine bis(S‐methyl­iso­thio­semicarbazone), as a potentially pentadentate ligand (N5), is coordinated as a tetradentate species, whereby one (deprotonated) iso­thio­semicarbazide moiety is coordinated in the usual way (1N4N), but the other (neutral) is bonded via the 2N atom only, the fourth ligator being the pyridine nitro­gen. The difference in coordination mode of the iso­thio­semicarbazide moiety is reflected in the 1N—2N bond lengths of 1.359 (4) and 1.379 (3) Å in the deprotonated and undeprotonated moieties, respectively. The structure contains three fused chelate rings in a 5:5:6 arrangement. The six‐membered ring has a non‐planar conformation.  相似文献

The title complex, poly­[bis­[N‐(2‐amino­ethyl)‐N‐methyl‐1,2‐ethane­di­amine]­hexa‐μ‐thio­cyanato‐tricadmium(II) monohydrate], [Cd3(NCS)6(medien)2]n·nH2O [medien is N,N‐bis(2‐amino­ethyl)­methyl­amine, C5H16N3], adopts a three‐dimensional inorganic polymeric network structure. Two cadmium centres (Cd1 and Cd2) are linked to each other via thio­cyanate bridges. The environment of the Cd1 atom involves only S atoms, making it soft, whereas the environment of the Cd2 atom involves only N atoms, making it hard.  相似文献
