2,2'-{1,1'-[Pentane-1,5-diylbis(oxy-nitrilo)]diethylidyne}di-1-naphthol.

ABSTRACT: The title compound, C(29)H(30)N(2)O(4), adopts a distorted Z configuration with respect to the oxime group, which is almost coplanar with the adjacent naphthalene ring [dihedral angle = 4.11?(2)°]. There is one half-mol-ecule in the asymmetric unit, with a crystallographic twofold rotation axis passing through the central C atom of the -CH=N-O-(CH)(5)-O-N=CH- bridge. Within the mol-ecule, the dihedral angle formed by the two naphthalene rings is 79.08?(3)°, and there are two intra-molecular O-H?N hydrogen bonds.

{2,2'-[3-Aza-pentane-1,5-diylbis(nitrilo-methyl-idyne)]dipyrrol-1-yl}(4-methyl-pyridine)cobalt(III) tetra-phenyl-borate.

Project description:The title compound, [Co(C(14)H(17)N(5))(C(6)H(7)N)](C(24)H(20)B) or [Co{(pyrrole)(2)dien}(4-Mepy)]BPh(4) where (pyrrole)(2)dien is 2,2'-[(3-aza-pentane-1,5-diylbis(nitrilo-methyl-idyne)]dipyrrole and 4-Mepy is 4-methyl-pyridine, contains a penta-dentate (pyrrole)(2)dien ligand furnishing an N(5) set, such that two of the pyrrole N atoms and two of the dien N atoms occupy the equatorial positions while one of the imine N atoms of the (pyrrole)(2)dien ligand occupies the axial position. The 4-methyl-pyridine ligand occupies an axial position trans to one of the imine N atoms of the penta-dentate ligand. In the observed conformation of the penta-dentate ligand, the pyrrole rings attain asymmetrical positions owing to the structural demands. The geometry of the resulting CoN(6) coordination can be described as distorted octa-hedral.

Dibromido[1,1'-dibutyl-2,2'-(pentane-1,1-di-yl)di-1H-benzimidazole]-copper(II).

Project description:In the title compound, [CuBr(2)(C(27)H(36)N(4))], the Cu(II) ion exhibits a distorted tetra-hedral coordination geometry provided by two bromide ions and by chelation of two imine N-atom donors from a bis-(benzimidazole) ligand. Chelation results in a six-membered boat-shaped ring which links the benzimidazole groups. Each bis-(benzimidazole) fragment contains three n-butyl substituents, two of which have the expected trans conformation; the third exhibits the higher-energy cis conformation, an orientation consistent with several short intra-molecular C-H⋯Br inter-actions. Essentially planar (r.m.s. deviations of 0.0101 and 0.0183 Å) benzimidazole groups are oriented so as to give the bis-(benzimidazole) fragment a V-shaped appearance in profile with the cis and trans n-butyl groups directed to opposite sides of the planes. In the crystal, columns of mol-ecules along the b-axis direction form layers parallel to the (202) planes. Within a given column, the mol-ecules are linked by C-H⋯Br hydrogen bonds. The mol-ecules in adjacent columns are also linked by inter-molecular C-H⋯π interactions, forming a three-dimensional network.

{1,1'-[(2,2-Dimethyl-propane-1,3-di-yl)bis-(nitrilo-methyl-idyne)]di-2-naphthol-ato}dioxidomolybdenum(VI) dichloro-methane 1.75-solvate.

Project description:In the crystal structure of the title compound, [Mo(C(27)H(24)N(2)O(2))O(2)]·1.75CH(2)Cl(2), the Mo(VI) ion is coordinated by two oxide O atoms and by two O and two N atoms of the tetra-dentate 1,1'-[(2,2-dimethyl-propane-1,3-di-yl)bis-(nitrilo-methyl-idyne)]di-2-naphtholate Schiff base ligand in a distorted octa-hedral configuration. The compound crystallizes with 1.75 mol-ecules of dichloro-methane per complex mol-ecule. In the crystal, symmetry-related mol-ecules are linked by a number of C-H⋯O inter-actions involving both the Schiff base ligand and the partly disordered dichloro-methane solvent mol-ecules, leading to the formation of a two-dimensional network extending parallel to (101).
