A V-shaped ligand Bis(2-benzimidazolymethyl)amine (bba) and its nickel(II) picrate (pic) complex, with composition [Ni(bba)(2)](pic)(2)·3MeOH, have been synthesized and characterized on the basis of elemental analyses, molar conductivities, IR spectra, and UV/vis measurements. In the complex, the Ni(II) ion is six-coordinated with a N(2)O(4) ligand set,(More)
In the title compound, [Cd(C(22)H(26)N(4)O)(2)](C(6)H(2)N(3)O(7))(2)·C(3)H(7)NO, the Cd(II) ion is coordinated by four N atoms and two O atoms from two tridentate 1,3-bis-(1-propyl-1H-benzimidazol-2-yl)-2-oxopropane ligands in a distorted octa-hedral coordination environment. There are significant differences in the chemically equivalent Cd-O bond lengths(More)

In the title compound, [Zn(NO(3))(2)(C(4)H(12)N(2)O)], the Zn(II) atom is N,O,N'-chelated by a 3-oxapentane-1,5-diamine ligand and is further coordinated by two nitrate anions in a distorted trigonal-bipyramidal geometry. Inter-molecular N-H⋯O hydrogen bonding is present in the crystal structure. A short O⋯O contact of 2.816 (8) Å is observed between the(More)
The crystal structure of the title compound, [Cd(C(29)H(29)N(5))(2)](C(6)H(2)N(3)O(7))(2), consists of Cd(II) complex cations and picrate anions. In the complex cation, the Cd(II) ion is chelated by two bis-(1-allyl-benzimidazol-2-ylmeth-yl)benzyl-amine (babb) ligands in a distorted octa-hedral geometry.
