Tetra-μ-benzoato-bis-{[4-(pyrrolidin-1-yl)pyridine]zinc(II)}

Abstract

The central part of the title centrosymmetric dinuclear complex, [Zn 2(C7H5O2)4(C 9H12N2)2], has a paddle-wheel conformation with four benzoate ligands bridging two symmetry-related Zn II ions. The distorted square-pyramidal coordination environment around the ZnII ion is completed by an N atom from a 4-(pyrrolidin-1-yl)pyridine ligand. The Zn⋯Zn separation of 2.9826 (12) Å does not represent a formal direct metal-metal bond. The ZnII ion is displaced by 0.381 (1) Å from the mean plane of the four basal O atoms. Two of the C atoms of the pyrrolidine ring are disordered over two sites with refined occupancies of 0.53 (2) and 0.47 (2).
