In the title centrosymmetric dimer, [Pb2(sbc)2(phen)2]·2H2O [sbc is the 2‐sulfonatobenzoate dianion (C7H4O5S) and phen is 1,10‐phenanthroline (C12H8N2)], each PbII ion is six‐coordinated by four O atoms, viz. carboxylate and sulfonate O atoms from two sbc anions, and two N atoms from a 1,10‐phenanthroline ligand. One 1,10‐phenanthroline ligand and the carboxylate group of one sbc ligand are chelated to each PbII cation, and the sulfonate group of the other sbc unit is monodentate. One O atom of the chelated carboxylate group also bridges to the other PbII cation, so that each pair of PbII ions is bridged by two sbc anions and has the same coordination environment, forming a dinuclear ring. Each pair of PbII ions is thus connected by two different kinds of bridges, namely a carboxylate short bridge and a carboxylate–sulfonate long bridge. There is also a special position of site symmetry at the centre of the two PbII cations. 相似文献

The triply bridged title dinuclear copper(II) compound, [Cu2(C2H3O2)(OH)(C12H8N2)2(H2O)](NO3)2·H2O, (I), consists of a [Cu2(μ2‐CH3COO)(μ2‐OH)(phen)2(μ2‐OH2)]2+ cation (phen is 1,10‐phenanthroline), two uncoordinated nitrate anions and one water molecule. The title cation contains a distorted square‐pyramidal arrangement around each metal centre with a CuN2O3 chromophore. In the dinuclear unit, both CuII ions are linked through a hydroxide bridge and a triatomic bridging carboxylate group, and at the axial positions through a water molecule. The phenanthroline groups in neighbouring dinuclear units interdigitate along the [010] direction, generating several π–π contacts which give rise to planar arrays parallel to (001). These are in turn connected by hydrogen bonds involving the aqua and hydroxide groups as donors with the nitrate anions as acceptors. Comparisons are made with isostructural compounds having similar cationic units but different counter‐ions; the role of hydrogen bonding in the overall three‐dimensional structure and its ultimate effect on the cell dimensions are discussed. 相似文献

In the centrosymmetric title polymer, catena‐poly[[bis[aqua(1,10‐phenanthroline‐κ2N,N′)lead(II)]‐di‐μ3‐5‐carboxy‐3‐sulfonatobenzoato‐1:2:1′κ4O3:O1,O1′:O1;2′:1:2κ4O1:O1,O1′:O3] dihydrate], {[Pb(C8H4O7S)(C12H8N2)(H2O)]·H2O}n, each seven‐coordinate lead(II) ion is bound by five O atoms from one water molecule and three 5‐sulfoisophthalate (sip) anions, and by two N atoms from a 1,10‐phenanthroline (phen) ligand. The sip sulfonate group is monodentate. One O atom of the sip carboxylate group is chelated to one Pb2+ cation, with the other also bridging an adjacent Pb2+ cation. The carboxyl group is uncoordinated. This unusual coordination results in a chain structure along the b axis, which is linked by strong intermolecular hydrogen bonds into a three‐dimensional network. 相似文献

Two different zinc sulfite compounds have been prepared through the decomposition of pyrosulfite–dithionite ions in aqueous solution, viz. a dimeric complex, di‐μ‐sulfito‐κ3O,O′:O′′;κ3O:O′,O′′‐bis[(4,4′‐dimethyl‐2,2′‐bipyridine‐κ2N,N′)zinc(II)] dihydrate, [Zn2(SO3)2(C12H12N2)2]·2H2O, (I), which was solved and refined from a twinned sample, and an extended polymer, poly[[aqua(1,10‐phenanthroline‐κ2N,N′)zinc(II)]‐μ3‐sulfito‐κ2O:O′:O′′‐zinc(II)‐μ3‐sulfito‐κ3O:O:O′], [Zn2(SO3)2(C12H10N2)(H2O)]n, (II). In (I), the dinuclear ZnII complex has a center of symmetry. The cation is five‐coordinate in a square‐pyramidal arrangement, the anion fulfilling a bridging chelating role. Compound (II) comprises two different zinc units, one being five‐coordinate (square pyramidal) and the other four‐coordinate (trigonal pyramidal), and two independent sulfite groups with different binding modes to the cationic centers. 相似文献

In the title coordination polymer, [Pb(C5H2N2O4)(H2O)]n, the PbII atom is seven‐coordinated by one N atom and five O atoms from four individual imidazole‐4,5‐dicarboxylate (HIDC2−) groups and one water molecule. It is interesting to note that the HIDC2− group serves as a bridging ligand to link the PbII atoms into a three‐dimensional microporous open‐framework. 相似文献

In the title compound, [Mn2(C7H6NO2)2(C2H3O2)2(C10H8N2)2], the two MnII atoms are each coordinated by one 2,2′‐bipyridyl molecule, one 4‐aminobenzoate ion and two acetate ions. The two Mn atoms exhibit different coordination environments: one is coordinated by two N and four O atoms, while the other is coordinated by two N and three O atoms. The two Mn atoms are bridged by two acetate ions in a syn–anti mode, with an Mn⋯Mn distance of 4.081 (1) Å. 相似文献

In the title compound, [Cd(C2O4)(C12H8N2)(C9H6O6)]·C6H5N3·H2O, the CdII atom has a distorted pentagonal–bipyramidal geometry, defined by two N atoms and five O atoms from bidentate 1,10‐phenanthroline ligands, oxalate ligands and benzene‐1,3,5‐tricarboxylic acid ligands. The oxalate ligands in the asymmetric unit possess inversion symmetry. The triazole molecule is not coordinated to the Cd atom. The structure of the title compound features a one‐dimensional chain running along the crystallographic a axis, and a three‐dimensional supramolecular network is formed via aromatic π–π interactions and hydrogen‐bonding interactions. 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

Two twisted 1,2‐bis(2‐pyridyl)ethyne ligands bridge two Cd2+ centers in the C2‐symmetric title complex, [Cd2(NO3)4(μ‐C12H8N2)2(H2O)2]. The bridging ligands arch across one another creating a `zigzag loop' molecular geometry. Two nitrate ions and a water molecule complete the irregular seven‐coordinate Cd‐atom environment. The dihedral angles between the equivalent pyridyl ring planes of the two independent ligands are 67.2 (1)°. Owater—H⃛Onitrate hydrogen bonding creates two‐dimensional layers parallel to the ab plane. 相似文献

The title compound, diaqua‐1κO,3κO‐di‐μ‐hydroxido‐1:2κ2O:O,2:3κ2O:O‐di‐μ‐methacrylato‐1:2κ2O:O′,2:3κ2O:O′‐bis(1,10‐phenanthroline)‐1κ2N,N′;3κ2N,N′‐tricopper(II) dinitrate dihydrate, [Cu3(C4H5O2)2(OH)2(C12H8N2)2(H2O)2](NO3)2·2H2O, has the central Cu atom on an inversion centre. The three CuII atoms are in a linear arrangement linked by methacrylate and hydroxide groups. The coordination environments of the CuII ions are five‐coordinated distorted square‐pyramidal for the outer Cu atoms and four‐coordinated square‐planar for the central Cu atom. All nitrate ions, hydroxide groups and water molecules are linked by hydrogen bonds, forming a linear structure. The complex exhibits ferromagnetic exchange coupling, which is helpful in elucidating magnetic interactions between copper ions and other metallic ions in heteronuclear complexes. 相似文献

In each of the zinc(II) complexes bis(acetylacetonato‐κ2O,O′)(1,10‐phenanthroline‐κ2N,N′)zinc(II), [Zn(C5H7O2)2(C12H8N2)], (I), and bis(acetylacetonato‐κ2O,O′)(2,2′‐bipyridine‐κ2N,N′)zinc(II), [Zn(C5H7O2)2(C10H8N2)], (II), the metal center has a distorted octahedral coordination geometry. Compound (I) has crystallographically imposed twofold symmetry, with Z′ = 0.5. The presence of a rigid phenanthroline group precludes intramolecular hydrogen bonding, whereas the rather flexible bipyridyl ligand is twisted to form an intramolecular C—H...O interaction [the chelated bipyridyl ligand is nonplanar, with the pyridyl rings inclined at an angle of 13.4 (1)°]. The two metal complexes are linked by dissimilar C—H...O interactions into one‐dimensional chains. The present study demonstrates the distinct effects of two commonly used ligands, viz. 1,10‐phenanthroline and 2,2′‐bipyridine, on the structures of metal complexes and their assembly. 相似文献

The title compound, [Cu2(C8H4O4)(C12H8N2)4](ClO4)2, was prepared from the hydrothermal reaction of CuCl2, 1,4‐dicyanobenzene, 1,10‐phenanthroline and water at 443 K. The compound is a dimer in which the cation lies about an inversion center. The terephthalate moiety acts as a bridging ligand and the phenanthrolines as terminal ligands. The unique Cu atom is coordinated by two O and four N atoms in a distorted octahedral geometry, with Cu—O distances of 1.955 (2) and 2.815 (2) Å, and Cu—N distances of 2.008 (2) to 2.216 (2) Å. 相似文献

The title compound, [Cu2(C9H10NO3)2(NO3)2(C10H8N2)(H2O)2]n, contains CuII atoms and l ‐tyrosinate (l ‐tyr) and 4,4′‐bipyridine (4,4′‐bipy) ligands in a 2:2:1 ratio. Each Cu atom is coordinated by one amino N atom and two carboxylate O atoms from two l ‐tyr ligands, one N atom from a 4,4′‐bipy ligand, a monodentate nitrate ion and a water molecule in an elongated octahedral geometry. Adjacent Cu atoms are bridged by the bidentate carboxylate groups into a chain. These chains are further linked by the bridging 4,4′‐bipy ligands, forming an undulated chiral two‐dimensional sheet. O—H...O and N—H...O hydrogen bonds connect the sheets in the [100] direction. This study offers useful information for the engineering of chiral coordination polymers with amino acids and 4,4′‐bipy ligands by considering the ratios of the metal ion and organic components. 相似文献

In the title compound, [Cu2(μ‐1,3‐N3)(N3)2(phen)4](N3)·4H2O (phen is 1,10‐phenanthroline, C12H8N2), each of the two Cu atoms is surrounded by two N atoms of two azide anions and by four N atoms of two 1,10‐phenanthroline ligands [Cu—N distances are 1.964 (3), 2.009 (3), 2.018 (3), 2.054 (3), 2.306 (3) and 2.759 (4) Å], forming an elongated CuN6 octahedron. An ideally linear μ1,3‐azide anion bridges two Cu atoms to form a dimeric structure with the central N atom located on a centre of inversion. Moreover, the adjacent dimeric units are connected by hydrogen‐bond interactions to produce one‐dimensional chains. A two‐dimensional supramolecular array is formed by π–π interactions between the aromatic rings of 1,10‐phenanthroline ligands of adjacent dimeric units. 相似文献

The title compound, [Zn(C7H4NO4)2(C12H8N2)(H2O)], has been synthesized. X‐Ray analysis reveals that it is a neutral zinc(II) mononuclear carboxylate complex based on mixed N‐ and O‐donor ligands. The Zn atom is five‐coordinate in a distorted trigonal–bipyramidal coordination environment involving two O atoms of two monodentate 2‐nitrobenzoate molecules, two N atoms of a 1,10‐phenanthroline molecule and one O atom of a water molecule. The axial positions are occupied by a carboxylate O atom from the 2‐nitrobenzoate ligand and an N atom from the 1,10‐phenanthroline ligand [N—Zn—O = 167.66 (9)°]. 相似文献

Two one‐dimensional (1D) coordination polymers (CPs), namely catena‐poly[[[aqua(2,2′‐bipyridine‐κ2N,N′)(nitrato‐κO)copper(II)]‐μ‐1,3‐bis(pyridin‐4‐yl)propane‐κ2N:N′] nitrate], {[Cu(NO3)(C10H8N2)(C13H14N2)(H2O)]·NO3}n ( 1 ), and catena‐poly[[[aqua(nitrato‐κO)(1,10‐phenanthroline‐κ2N,N′)copper(II)]‐μ‐1,3‐bis(pyridin‐4‐yl)propane‐κ2N:N′] nitrate], {[Cu(NO3)(C12H8N2)(C13H14N2)(H2O)]·NO3}n ( 2 ), have been synthesized using [Cu(NO3)(NN)(H2O)2]NO3, where NN = 2,2′‐bipyridine (bpy) or 1,10‐phenanthroline (phen), as a linker in a 1:1 molar ratio. The CPs were characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and single‐crystal X‐ray structure determination. The 1,3‐bis(pyridin‐4‐yl)propane (dpp) ligand acts as a bridging ligand, leading to the formation of a 1D polymer. The octahedral coordination sphere around copper consists of two N atoms from bpy for 1 or phen for 2 , two N atoms from dpp, one O atom from water and one O atom from a coordinated nitrate anion. Each structure contains two crystallographically independent chains in the asymmetric unit and the chains are linked via hydrogen bonds into a three‐dimensional network. 相似文献

A novel 1D polymeric lead(II) complex containing the first Pb2‐(μ‐N3)2 motif, [Pb(phen)(μ‐N3)(μ‐NO3)]n (phen = 1,10‐phenanthroline), has been synthesized and characterized. The single‐crystal X‐ray data showed the coordination number of Pb2+ ions to be eight (PbN4O4) with the Pb2+ ions having “stereo‐chemically active” electron lone pairs; the coordination sphere is hemidirected. The chains interact with each other via π‐π interactions to create a 3D framework. 相似文献
