Caesium tetrasilver dizinc nonathiocyanate, Cs[Ag4Zn2(SCN)9], forms a continuous structure, where the Ag atoms and the S atoms of the thiocyanate groups form chains which run along [101]. These chains are bonded together through the Cs and Zn atoms. It is not possible to distinguish between space groups P1 and P, but, if the latter space group is correct, the structure contains a thiocyanate group disordered across a centre of inversion. The structure is described in space group P, in which the Cs atom also lies on a centre of inversion. 相似文献

The title compound, {(C6H14N2)[Ag(NCS)3]}n, is a polymeric silver(I) complex. The AgI atom is hexacoordinated by the S atoms of six thiocyanate anions, with each thiocyanate S atom acting in a bridging mode to link the Ag atoms together. The unique AgI atom lies at a cell origin and has crystallographically imposed symmetry. The diazonia[2.2.2]octane molecule lies about a site with imposed symmetry with the unique N atom on a threefold axis. The S and N atoms of the thiocyanate ligands sit on a mirror plane and a threefold axis, respectively. The crystal structure consists of one‐dimensional chains, which are stabilized by N—H⋯N hydrogen bonds to form a three‐dimensional network. 相似文献

The title complex, [Cu(C11H14BrN2O)(NCS)]n, is an interesting thiocyanate‐bridged polynuclear copper(II) compound, which crystallizes with two independent molecules in the asymmetric unit. Each CuII atom is five‐coordinate in a square‐pyramidal configuration, with one O and two N atoms of one Schiff base ligand and one terminal N atom of a bridging thiocyanate ligand defining the basal plane, and one terminal S atom of another bridging thiocyanate ligand occupying the apical position. The {4‐bromo‐2‐[2‐(dimethylamino)ethyliminomethyl]phenolato}copper(II) units are linked by the bridging thiocyanate ligands, forming polymeric chains running along the a axis. There are weak intermolecular C—H⋯O and C—H⋯S hydrogen bonds between the chains in the crystal structure. 相似文献

The title complex, [Cd2(C13H9Cl2N2O)2(NCS)2]n, is a novel thiocyanate‐bridged polynuclear cadmium(II) compound. The CdII atom is six‐coordinated in a distorted octahedral configuration, with one O and two N atoms of one Schiff base molecule and one terminal S atom of a bridging thiocyanate ligand defining the equatorial plane, and one terminal N atom of another bridging thiocyanate ligand and one O atom of another Schiff base molecule occupying axial positions. Adjacent inversion‐related [2,4‐dichloro‐6‐(2‐pyridylmethyliminomethyl)phenolato]cadmium(II) moieties utilize bridging phenolate and thiocyanate groups to form polymeric chains running along the b axis. 相似文献

The CuI cations in the title compound, [Cu(NCS)(C6H6N2O)2]n, are coordinated by N atoms from each of two mirror‐related nicotinamide ligands, as well as by one N atom of one thiocyanate ligand and one S atom of a symmetry‐related thiocyanate ligand, within a slightly distorted tetrahedron. The CuI cations and the thiocyanate anions are located on a crystallographic mirror plane and the nicotinamide ligands occupy general positions. The CuI cations are connected by the thiocyanate anions to form chains in the direction of the crystallographic a axis. These chains are connected by hydrogen bonds between the amide H atoms and the O atoms of adjacent nicotinamide ligands, to give a three‐dimensional structure. 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

In the title complex, {[MnHg(SCN)4(H2O)2]·2C4H9NO}n, each Mn atom is octahedrally coordinated to four equatorial thiocyanate N atoms and two axial water O atoms. The Mn atom and two O atoms lie on a twofold axis. Two kinds of crystallographically independent Hg atoms (denoted Hg1 and Hg2) are tetrahedrally coordinated with four thiocyanate S atoms and each Hg atom lies on a axis. N,N‐Dimethylacetamide molecules are connected to coordinated water molecules through hydrogen bonds. Each pair of Mn and Hg atoms is bridged via one thiocyanate ion. An Mn2Hg1Hg2(SCN)4 16‐membered ring is formed as a unit and the four metal atoms are in a chair‐form tetrahedral arrangement. The units are linked with one another and form infinite two‐dimensional networks. 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

The crystal structures of dicaesium nickel disilver hexathiocyanate dihydrate, Cs2NiAg2(SCN)6·2H2O, (I), and caesium nickel trithiocyanate, CsNi(SCN)3, (II), have been determined by single‐crystal X‐ray diffraction at 273 K. Compounds (I) and (II) are monoclinic, with P21/c and P21/n symmetry, respectively. In (I), the Ni atom lies on an inversion centre; in (II), there are two independent Ni atoms, each of which lies on an inversion centre. The coordination polyhedra and the bonding schemes in the structures are discussed. 相似文献

The anions of the title compounds contain [Ag(SCN)4] units, with the S atoms coordinating to Ag+ in a tetrahedral arrangement. Whereas in the isolated anions of tripotassium tetrathiocyanatoargentate(I), K3[Ag(SCN)4], (I), all SCN? groups are bonded as terminal ligands, in tetrapotassium di‐μ‐thiocyanato‐S:S‐bis[dithiocyanatoargentate(I)], K4[Ag2(SCN)6], (II), two AgS4 tetrahedra share one common edge. In poly[potassium [argentate(I)‐di‐μ‐thiocyanato‐S:S]], K[Ag(SCN)2], (III), edge‐ and vertex‐sharing of AgS4 tetrahedra results in infinite [Ag(SCN)2]? layers. 相似文献

We present the first example of a compound containing Ba2+, C2O42−, water and some additional halide or pseudo‐halide anions, viz. hexa‐μ2‐aqua‐μ6‐oxalato‐dibarium(II) diisothiocyanate, {[Ba2(C2O4)(H2O)6](NCS)2}n. The structure consists of positively charged planar covalent layers of Ba2+ cations, oxalate anions and water molecules. The first coordination sphere of the Ba2+ cation contains six water molecules and four O atoms from two planar oxalate anions. The oxalate anion lies on an inversion centre and is coordinated to six Ba2+ cations, each donor O atom being bonded to two cations. Pairs of water molecules are coordinated by two Ba2+ cations. The layers are interspersed with non‐coordinated NCS− anions. 相似文献

In contrast to former morphological studies, the results presented here show that calcium(II) thiosulfate hexahydrate, CaS2O3·6H2O, crystallizes centrosymmetrically in the pinacoidal class (point group ). The structure is characterized by chains, parallel to [100], of alternating S2O3 and Ca(H2O)6O2 groups sharing common O atoms. The composition of each chain link is [Ca(H2O)6(S2O3)]. The geometry is analysed and compared in detail with the structural features of monoclinic strontium(II) thiosulfate pentahydrate, SrS2O3·5H2O, which forms layers, parallel to (100), of alternating S2O3 and Sr(H2O)4O5 groups connected via common O atoms and O–O edges. Each layer contains [Sr(H2O)3O(S2O3)]∞ as the unique repeat unit. 相似文献

Using 2‐aminomethyl‐1H‐benzimidazole as the ligand, a new thiocyanate‐bridged copper(II) complex, namely bis(2‐aminomethyl‐1H‐benzimidazole‐κ2N2,N3)dithiocyanatocopper(II),[Cu(NCS)2(C8H9N3)], has been synthesized and structurally characterized. The Cu atom is five‐coordinated and exhibits a distorted square‐pyramidal geometry. The thiocyanate ions (NCS−) act as either bridging or terminal ligands. The bridging NCS− ligands connect neighboring Cu atoms, constructing chains, while the terminal NCS− ligands form hydrogen bonds with amine H atoms, leading to a complicated network. 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:S;κ2S: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

The title complex, [Ag4(C7H5O3)2(C8H6N2)4(C7H6O3)4], lies about an inversion centre and has a unique tetranuclear structure consisting of four AgI atoms bridged by four N atoms from two 1,8‐naphthyridine (napy) ligands to form an N:N′‐bridge and four O atoms from two salicylate (SA) ligands to form an O:O′‐bridge. The Ag atoms have distorted octahedral coordination geometry. The centrosymmetric Ag4 ring has Ag—Ag separations of 2.772 (2) and 3.127 (2) Å, and Ag—Ag—Ag angles of 107.70 (4) and 72.30 (4)°. All SA hydroxy groups take part in intramolecular O—H⋯O hydrogen bonding. In the crystal packing, the napy rings are oriented parallel and overlap one another. These π–π interactions, together with weak intermolecular C—H⋯O contacts, stabilize the crystal structure. 相似文献
