Trans-Bis(acetato-0)bis(4-methylpyridine-N)copper(II)

The structure of trans-bis(acetato-O)bis (4-methylpyridine-N)copper(II), (Cu(C2H3O2)2(C6H7N)2), reported herein, represents a monomeric parent acetate complex with a distorted square-planar arrangement of acetate and 4-methylpyridine ligands around the Cu atom with the following distances and angles: Cu-N = 2.027(4) and Cu-O(1) = 1.950 (3) A; O(1)-Cu-N = 89.1 (2) and O(1)-Cu-N' = 90.0(2)deg. The Cu atom resides on a center of inversion. the most important dihedral angles are the angle between the 4-methylpyridine plane and the acetate plane (O(1), O(2), C(21), and C(22)), 78.2 deg, and the angle between the 4-methylpyridine ring and the coordination plane (Cu, N, O(1)), 31.6 deg.
