Bis[μ-N-(3-meth-oxy-2-oxidobenzyl-idene-1:2κ(2)O(2):O(2))-l-isoleucinato-2κ(2)N,O]bis-(1,10-phenanthroline-1κ(2)N,N')dinickel(II) methanol tetra-solvate trihydrate.

ABSTRACT: In the title complex, [Ni(2)(C(14)H(17)NO(4))(2)(C(12)H(8)N(2))(2)]·4CH(3)OH·3H(2)O, the two Ni(II) ions are bridged by two Schiff base anions, leading to a dinuclear complex. One Ni(II) ion is six-coordinated by four O atoms and two N atoms of two tridentate Schiff base ligands derived from the condensation of l-isoleucine and o-vanillin. The other Ni(II) ion is six-coordinated by four N atoms of two 1,10-phenanthroline ligands and two O atoms of the Schiff base ligands. In the crystal, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds lead to a three-dimensional structure. Intra-molecular C-H⋯O hydrogen bonds are also present. One of the methyl groups of the l-isoleucinate moieties is disordered over two sets of sites with an occupancy ratio of 0.687 (19):0.313 (19) and two methanol mol-ecu
