The Methyl Group at C 2 Carbon in {(2‐C 4 H 3 S)–C 2 (Me)=N–NH–C 1 (=S)NH 2 } Alters Iodide‐Bridging to Sulfur‐Bridging in Copper(I) Iodide Complexes

The presence of methyl group at C 2 carbon in {(2‐C 4 H 3 S)–C 2 (Me)=N–NH–C 1 (=S)NH 2 } leads to the formation of a sulfur‐bridged dinuclear complex [Cu 2 (μ‐S–Hattsc) 2 (η 1 ‐I) 2 (Ph 3 P) 2 ] · 2H 2 O ( 1 ), in reaction of copper(I) iodide with the 2‐acetylthiophene thiosemicarbazone (Hattsc), unlike the usual iodo‐bridging in the absence of methyl substituent at C 2 carbon. Water molecules are entrapped in eighteen membered cavities of 1D network.
