Abstract

The chain structure of a tetranuclear zinc(II) cluster [Zn4Q6(Ox)]0.5n ([Zn4 (C9H6NO)6(C2O4)]0.5n) (1) (Q = 8- hydroxyquinoline anion, Ox = oxalate dianion) was determined by X-ray crystallography and characterized by elemental analysis, IR spectroscopy and thermal analysis. It crystallizes in the monoclinic system, space group P21/n (No. 14), with the lattice parameters a = 13.2222(15) ?, b = 11.0566(12) ?, c = 16.2224(18) ?, ? = 92.1770(10)?, V = 2369.9(5) ?3, Z = 4, Mr = 607.23 g mol-1, Dc = 1.702 g cm-3. The tetranuclear zinc(II) clusters form 1D polymeric chains parallel to the b-axis. The ?-? stacking interactions involving aryl rings support the formation of the 1D polymeric structure. The neighboring polymeric chains are connected by C-H???? interactions.
