Bis(μ-hexadecanoato-κ2O:O)bis[(2,2′-bipyridine-κ2N,N′)(hexadecanoato-κO)copper(II)] methanol disolvate

Abstract

The asymmetric unit of the title compound, [Cu2(C16H31O2)4(C10H8N2)2]·2CH3OH, contains one half-mol­ecule of the metal complex solvated by a methanol mol­ecule. In the complex, two of the metal atoms are doubly bridged by two monodentate bridging hexa­deca­noate ligands around a center of inversion. The square-pyramidal geometry around each CuII ion is completed by a terminal hexa­deca­noate O atom and two N atoms from a 2,2′-bipyridine ligand. The alkyl chains of the carboxyl­ate ligands are arranged in a parallel manner with an all-trans conformation. In the crystal, a π–π inter­action formed by the bipyridine rings [centroid–centroid separation = 3.7723 (17) Å] and inter­molecular C—H⋯O hydrogen bonds link the complex mol­ecules into infinite chains along the b axis. An O—H⋯O interaction between the methanol solvate and one of the carboxylate O atoms is also observed.
