Tetra-μ-acetato-κ8 O:O′-bis[(N-ethylpyrimidin-2- amine)copper(II)](Cu-Cu)

Abstract

In the centrosymmetric title molecule, [Cu2(CH3COO) 4-(C6H9N3)2], each of the four acetate groups bridges a pair of CuII atoms [Cu-Cu = 2.6540 (4) Å]. The distorted octahedral geometry of the metal atom is completed by an N-donor atom of the N-ethylpyrimidin-2-amine ligand: an intramolecular N-H⋯O hydrogen links its N-H group to an acetate carboxylate O atom. In the crystal, C-H⋯O interactions link the molecules into a supramolecular chain along the b axis.
