title: Bis(2,2'-bipyridine)bis-{μ(3)-cis-N-(2-carboxyl-atophen-yl)-N'-[3-(dimethyl-amino)prop-yl]oxamidato(3-)}-bis(per-chlorato)-tetra-nickel(II) methanol disolvate.
abstract: In the title methanol disolvate complex, [Ni(4)(C(14)H(16)N(3)O(4))(2)(ClO(4))(2)(C(10)H(8)N(2))(2)]·2CH(3)OH, the neutral tetra-nickel(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.
