Bis(2,2′-bipyridine)bis­{μ3-cis-N-(2-carboxyl­atophen­yl)-N′-[3-(dimethyl­amino)prop­yl]oxamidato(3−)}­bis(per­chlorato)­tetra­nickel(II) methanol disolvate

摘要

In the title methanol disolvate complex, [Ni4(C14H16N3O4)2(ClO4)2(C10H8N2)2]·2CH3OH, the neutral tetra­nickel(II) system lies on a centre of inversion. The polyhedron around each Ni(II) atom is a square pyramid. The separations of the Ni atoms bridged by the oxamide and carboxyl groups are 5.227 (9) and 5.268 (6) Å, respectively. In the crystal structure, a two-dimensional supramolecular network structure involving O—H⋯O and C—H⋯O hydrogen bonding is observed.
