Bis[μ-N-(3-meth­oxy-2-oxidobenzyl­idene-1:2κ²O²:O²)-L-isoleucinato-2κ²N,O]bis­(1,10-phenanthroline-1κ²N,N′)dinickel(II) methanol tetra­solvate trihydrate

In the title complex, [Ni₂(C₁₄H₁₇NO₄)₂(C₁₂H₈N₂)₂]·4CH₃OH·3H₂O, 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, inter­molecular O—H...O and C—H...O hydrogen bonds lead to a three-dimensional structure. Intra­molecular 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 mol­ecules are half-occupied.

(Methanol-κO)(methano­lato-κO)oxido[N-(2-oxidobenzyl­idene)isoleucinato-κ³O,N,O′]vanadium(V)

In the title complex, [V(C₁₃H₁₅NO₃)O(CH₃O)(CH₃OH)], the V^V atom is six-coordinated by a tridentate O,N,O′-donor ligand, derived from the condensation of salicyl­aldehyde and L-isoleucine, a vanadyl O atom, a methano­late O atom and a methanol O atom in a distorted octa­hedral geometry. The asymmetric unit contains two complex mol­ecules. In the crystal, inter­molecular O—H...O and C—H...O hydrogen bonds connect the mol­ecules into a one-dimensional chain along [100].
