Abstract

The one-pot reactions between anhydrous zinc acetate, diethyl or di-n-propyl sulfite, and tetraalkylammonium iodide (120 °C, 12 h) proceed through sulfur-centered Arbuzov-type rearrangement to afford [R1 4N]2[Zn(OSO2R)4] [R1, R = Et (1); R1 = nBu, R = nPr (2)] bearing alkanesulfonate groups bound to the metal center. The zincate salts 1 and 2 are used as precursors for the synthesis of neutral and cationic coordination complexes, namely, [Zn(OSO2Et)2(bipy)(dmso)2] (3; bipy = 4,4'-bipyridine, dmso = dimethyl sulfoxide), [Zn(OSO2nPr)2(bipy)2]·dmso·H2O (4), [Zn(bipy)(H2O)4](OSO2Et)2 (5), [Zn(H2O)6](OSO2Et)2 (6), and [Zn(H2O)6](OSO2nPr)2 (7). X-ray crystallographic studies of 3-7 reveal that the alkanesulfonate groups act as prolific H-bond acceptors and assist the transformation of zero-, one-, or two-dimensional coordination frameworks into three-dimensional structural motifs.
