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 R 1 4 N 2 Zn(OSO 2 R) 4 R 1 , R = Et ( 1 ); R 1 = n Bu, R = n Pr ( 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(OSO 2 Et) 2 (bipy)(dmso) 2 ( 3 ; bipy = 4,4′‐bipyridine, dmso = dimethyl sulfoxide), Zn(OSO 2 n Pr) 2 (bipy) 2 · dmso · H 2 O ( 4 ), Zn(bipy)(H 2 O) 4 (OSO 2 Et) 2 ( 5 ), Zn(H 2 O) 6 (OSO 2 Et) 2 ( 6 ), and Zn(H 2 O) 6 (OSO 2 n Pr) 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.
