Structure of tetra­kis­(μ-deca­noato-κ2O:O′)bis­­[(4-methyl­pyridine-κN)copper(II)], a dimeric copper(II) complex

The 4-methylpyridine (4-Mepy) based dimeric copper(II) carboxylate complex [Cu2(C10H19O2)4(C6H7N)2] or [Cu2(-O2CC9H19)4(4-Mepy)2] crystallizes with triclinic (P1) symmetry. The two CuII ions exhibit a distorted square-pyramidal environment and are connected into a centrosymmetric paddle-wheel dinuclear cluster [CuCu = 2.6472 (8) A˚ ] via four bridging carboxylate ligands arranged in the syn–syn coordination mode. The apical positions around the paddle-wheel copper centers are occupied by the N atoms of the 4-methylpyridine ligands. The structure exhibits disorder of the terminal alkyl carbon atoms in the decanoate chains.
