چکیده
The two unique Ni(II) atoms of the title complex, [MnNi(2)(C(11)H(8)N(3)O(6))(2)(H(2)O)(4)]·4H(2)O, have a slightly distorted square-planar coordination environment with a tetra-dentate N-(5-nitro-2-oxidobenzyl-idene)glycylglycinate Schiff base trianion. The Ni(II) atoms are coordinated by one phenolate O atom, one imine N atom, one amido N atom and one carboxyl-ate O atom. The Mn(II )atom is connected via the carboxyl-ate groups, forming a hetero-trinuclear Ni(II)-Mn(II)-Ni(II) system. The Mn(II) atom is six-coordinated in an octa-hedral geometry by four O atoms from two carboxyl-ate groups and four water mol-ecules. The Ni(II)-Mn(II)-Ni(II) hetero-trinuclear mol-ecules are stacked in the crystal and cross-linked through O-H⋯O hydrogen bonds.
