Tetra-kis(1-benzyl-1H-imidazole)dichlorido-nickel(II).

ABSTRACT: In the title compound, [NiCl(2)(C(10)H(10)N(2))(4)], the Ni(II) ion is located on an inversion center being coordinated by four N atoms from two pairs of symmetry-related 1-benzyl-1H-imidazole ligands and two chloride anions in a distorted octa-hedral geometry. Weak inter-molecular C-H?Cl hydrogen bonds link the mol-ecules into layers parallel to the ab plane.

cis-Di-aqua-tetra-kis-(1-butyl-1H-imidazole-?N (3))nickel(II) dichloride.

Project description:In the title compound, [Ni(C7H12N2)4(H2O)2]Cl2, the nickel(II) ion has a distorted octa-hedral coordination environment. It is surrounded by three N atoms and one O atom occupying the equatorial plane, and one N and one O atom in the axial positions. The imidazole ring systems are inclined to one another with dihedral angles varying between 38.3?(4) and 74.1?(4)°. In the crystal, mol-ecules are linked via O-H?Cl hydrogen bonds involving one Cl(-) anion and the water mol-ecule in the equatorial plane, forming an inversion dimer-like arrangement. The water mol-ecule in the axial position is hydrogen-bonded to both Cl(-) anions. There are also a number of C-H?Cl hydrogen bonds present, forming a three-dimensional structure. All four alkyl chains are disordered over two positions with refined occupancy ratios of 0.395?(15):0.605?(15), 0.658?(14):0.342?(14), 0.332?(11):0.668?(11) and 0.622?(12):0.378?(12).

Poly[[tetra-aqua-bis-(?(3)-1H-imidazole-4,5-dicarboxyl-ato)tetra-kis-(?(2)-1H-imidazole-4,5-dicarboxyl-ato)tricobalt(II)diytterbium(III)] dihydrate].

Project description:The asymmetric unit of the title compound, {[Co(3)Yb(2)(C(5)H(2)N(2)O(4))(6)(H(2)O)(4)]·2H(2)O}(n), contains one Yb(III) ion, two Co(II) ions (one situated on an inversion centre), three imidazole-4,5-dicarboxyl-ate ligands, two coordinated water mol-ecules and one uncoordinated water mol-ecule. The Yb(III) ion is seven-coordinated, in a monocapped trigonal prismatic coordination geometry, by six O atoms from three imidazole-4,5-dicarboxyl-ate ligands and one water O atom. Both Co(II) ions are six-coordinated in a slightly distorted octa-hedral geometry. The Co(II) ion that is located on an inversion center is coordinated by two O atoms from two water mol-ecules, as well as two O atoms and two N atoms from two imidazole-4,5-dicarboxyl-ate ligands. The second Co(II) ion is bonded to four O atoms and two N atoms from four imidazole-4,5-dicarboxyl-ate ligands. These metal coordination units are connected by bridging imidazole-4,5-dicarboxyl-ate ligands, generating a three-dimensional network. The crystal structure is further stabilized by N-H?O, O-H?O and C-H?O hydrogen-bonding inter-actions involving the water mol-ecules and the imidazole-4,5-dicarboxyl-ate ligands.

Hexa-kis-(1H-imidazole-?N)iron(II) sulfate-1H-imidazole (1/2).

Project description:The asymmetric unit of the title compound, [Fe(C(3)H(4)N(2))(6)]SO(4)·2C(3)H(4)N(2), contains two complex cations, two sulfate anions and four imidazole mol-ecules.

The Fe-N distances [2.184?(4)-2.218?(4)?Å] point to a high-spin state of the Fe(2+) ions. N-H?O hydrogen bonds between the ionic components generate a three-dimensional framework containing corrugated channels along [001], which are filled by N-H?N hydrogen-bonded imidazole chains.
