Catena-Poly[[diformatocopper(II)]-?-1,4-bis-(imidazol-1-yl)benzene].

ABSTRACT: In the title compound, [Cu(CHO(2))(2)(C(12)H(10)N(4))], the Cu(II) ion lies on an inversion center and is coordinated by two formate O atoms and two N atoms from two 1,4-bis-(imidazol-1-yl)phenyl ligands (L), forming a square-planar coordination environment. The linear mol-ecule L acts as a bidente bridging ligand, connecting the metal atoms into a chain along [101].

Project description:In the title one-dimensional coordination polymer, [ZnCl(2)(C(12)H(10)N(4))](n), the Zn(II) atom (site symmetry 2) is coordinated by two chloride ions and two 1,4-bis-(imidazol-1-yl)benzene ligands, generating a distorted tetra-hedral ZnCl(2)N(2) geometry for the metal ion. The bridging ligand, which is completed by crystallographic inversion symmetry, links the Zn(II) atoms into zigzag chains propagating in [101]. Within the ligand, the dihedral angle between the central benzene ring and terminal imidazole ring is 27.82?(13)°.

Poly[[?-1,4-bis-(imidazol-1-ylmeth-yl)benzene]bis-(?(4)-cyclo-hexane-1,4-dicarboxyl-ato)dinickel(II)].

Project description:The structure of the polymeric title compound, [Ni(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), features a five-coordinate Ni(II) centre defined by four carboxyl-ate O atoms from two different cyclo-hexane-1,4-dicarboxyl-ate (chdc) ligands and an N atom from one end of a 1,4-bis-(imidazol-1-ylmeth-yl)benzene (1,4-bix) mol-ecule. The NO(4) coordination geometry is distorted square-pyramidal with the N atom in the apical position. Each end of the chdc ligand links pairs of Ni(II) atoms into a paddle-wheel assembly, i.e. Ni(2)(O(2)CR')(4). These are connected into rows owing to the bridging nature of the chdc ligands, and the rows are connected into a two-dimensional grid via the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions of equal occupancy were discerned for the -H(2)C(C(6)H(4))CH(2)- residue.

Project description:In the title coordination polymer, [Cd(C(9)H(6)O(4))(C(12)H(10)N(4))(H(2)O)](n), the Cd(II) atom has a NO(6) donor set and is coord-inated by five carboxyl-ate O atoms from three different 5-methyl-1,3-phenyl-enediacetate (pda(2-)) anions, one O atom from a water mol-ecule and one N atom from a 1,4-bis-(1H-imidazol-4-yl)benzene (L) ligand, displaying a highly distorted penta-gonal-bipyramidal geometry. Each pda(2-) anion acts as a μ(3)-bridge, linking Cd(II) atoms to form one-dimensional slabs extending parallel to [010]. In the crystal, adjacent mol-ecules are linked through N-H⋯N and N-H⋯O hydrogen bonds into a three-dimensional network.

Project description:In the title coordination polymer, [Cd(C(8)H(11)O(4))(2)(C(14)H(14)N(4))](n), the Cd atom (site symmetry 2) is six-coordin-ated by two O,O'-bidentate 4-carboxy-cyclo-hexa-necarboxyl-ate (Hchdc) ligands and two N atoms from two different 1,4-bis-(imidazol-1-ylmeth-yl)benzene (1,4-bix) mol-ecules in a very distorted cis-CdN(2)O(4) octa-hedral environment. The 1,4-bix mol-ecules act as bridging ligands that bind two Cd(II) atoms, thus forming an infinite chain propagating in [100], which is decorated by the Hchdc anions. The structure is completed by O-H?O hydrogen bonds, which link the chains together.

Poly[[?(2)-1,4-bis-(imidazol-1-ylmeth-yl)benzene]bis-(?(4)-cyclo-hexane-1,4-dicarboxyl-ato)dicobalt(II)].

Project description:In the title compound, [Co(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), the two Co(II) atoms are both five-coordinated by four carboxyl-ate O atoms, derived from two different cyclo-hexane-1,4-dicarboxyl-ate (chdc) ligands, and an N atom, derived from one end of a 1,4-bis-(imidazol-1-ylmeth-yl)benzene mol-ecule (1,4-bix), in a distorted square-pyramidal environment. Each end of the chdc ligand links pairs of Co(II) atoms into a paddle-wheel assembly, i.e. Co(2)(O(2)CR')(4); these are connected into rows because of the bridging nature of the chdc ligands, and the rows are further connected into a two-dimensional layer through the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions were discerned for the -CH(2)(C(6)H(4))CH(2)- residue, with the major component having a site-occupancy factor of 0.512?(9).

Poly[bis-[?-1,4-bis-(imidazol-1-ylmeth-yl)benzene]-dichloridomanganese(II)].

Project description:In the crystal structure of the title compound, [MnCl(2)(C(14)H(14)N(4))(2)](n), the Mn(II) atom, lying on an inversion center, is coordinated by four N atoms from four 1,4-bis-(imidazol-1-ylmeth-yl)benzene (bimb) ligands and two Cl(-) anions in a distorted octa-hedral geometry.

Weak C-H?? inter-actions are present in the crystal structure.

catena-Poly[[zinc(II)-bis-[?-1,3-bis-(imidazol-1-ylmeth-yl)benzene-?N:N]] dinitrate methanol solvate].

Project description:In the title coordination compound, {[Zn(C(14)H(14)N(4))(2)](NO(3))(2)·CH(3)OH}(n), the cationic complex forms a looped chain containing 24-membered M(2)L(2) rings. The ligand adopts two distinct conformations that are alternated in subsequent loops. The Zn(II) ion displays a slightly distorted tetra-hedral geometry being coordinated by four N atoms from four 1,3-bis-(imidazol-1-ylmeth-yl)benzene ligands. The nitrate ions and methanol solvent mol-ecules are located between adjacent double-stranded chains and participate in an extensive net of O-H?O and C-H?O hydrogen bonds. The resulting three-dimensional assembly is further stabilized by ?-? inter-actions between benzene rings [centroid-centroid distances = 3.878?(2) and 3.853?(2)?Å].

catena-Poly[[dichloridomercury(II)]-?-1,4-bis-[(pyridin-2-yl)meth-oxy]benzene-?N:N'].

Project description:In the title compound, [HgCl(2)(C(18)H(16)N(2)O(2))](n), the Hg(II) atom is four-coordinated in a distorted tetra-hedral environment defined by two Cl atoms and two N atoms from two 1,4-bis-(pyridin-2-ylmeth-oxy)benzene ligands. The ligand shows a non-coplanar conformation, in which the dihedral angles between the two terminal pyridine rings and the linking benzene ring are 7.275?(17) and 74.020?(14)°. The flexible ligands link the Hg(II) atoms into a chain running along [010], with an Hg?Hg separation of 10.335?(5)?Å, which is equal to the b axis. The chains are connected by C-H?O and C-H?Cl hydrogen bonds.
