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

ABSTRACT: The central part of the title centrosymmetric dinuclear complex, [Zn(2)(C(7)H(5)O(2))(4)(C(9)H(12)N(2))(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 Zn(II) 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 Zn(II) 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).

Tetra-kis(?-4-methyl-benzoato-?O:O')bis-{[4-(dimethyl-amino)pyridine-?N]zinc(II)}.

Project description:In the centrosymmetric title binuclear complex, [Zn(2)(C(8)H(7)O(2))(4)(C(7)H(10)N(2))(2)], the Zn atoms [Zn?Zn = 3.0287?(6)?Å] are bridged by four 4-methyl-benzoate ligands. The four nearest O atoms around each Zn(II) atom form a distorted square-planar arrangement with the distorted square-pyramidal coordination completed by the pyridine N atom of the 4-(dimethyl-amino)pyridine ligand. In the crystal structure, weak inter-molecular C-H?O inter-actions link the mol-ecules into infinite chains. The chains are further linked by weak C-H?? inter-actions, forming a three-dimensional network.

Tetra-?-benzoato-bis-{[trans-1-(2-pyrid-yl)-2-(4-pyrid-yl)ethyl-ene]zinc(II)}.

Project description:The paddle-wheel-type centrosymmetric dinuclear title complex, [Zn(2)(C(7)H(5)O(2))(4)(C(12)H(10)N(2))(2)], contains four bridging benzoate groups and two terminal trans-1-(2-pyrid-yl)-2-(4-pyrid-yl)ethyl-ene (L) ligands.

The Zn(II) atom is 0.372?Å out of the plane of the four coordinating O atoms.
