ABSTRACT

The dinuclear title compound, [In2(CH3)2(C7H7S)4] or [Me(2-MeC6H4S)In-μ-(2-MeC6H4S)2InMe(2-MeC6H4S)], was prepared from the 1:2 reaction of Me3In and 2-MeC6H4SH in toluene. Its crystal structure exhibits a four-membered In2S2 ring core via bridging (2-MeC6H4S) groups. The dimeric units are further associated into a one-dimensional polymeric structure extending parallel to the a axis via inter­molecular In⋯S contacts. The In atoms are then in distorted trigonal–bipyramidal CS4 bonding environments.

Mentions: The asymmetric unit comprises the dinuclear compound, [Me(2-MeC6H4S)In-μ-(2-MeC6H4S)2InMe(2-MeC6H4S)], (I) (Fig. 1 ▸). The two unique indium atoms are each bonded to a methyl carbon atom, and one terminal and one bridging (2-MeC6H4S) group, generating a nearly square-planar four-membered In2S2 ring core [S2—In1—S3 = 88.28 (6), In1—S2—In2 = 91.86 (6), S2—In2—S3 = 87.02 (6), In1—S3—In2 = 92.58 (7)°]. The In atoms are in distorted trigonal–pyramidal CS3 bonding environments [C1—In1—S1 = 127.3 (2), C1—In1—S2 = 113.1 (3), S1—In1—S2 = 114.66 (7), C1—In1—S3 = 105.7 (2), S1—In1—S3 = 96.94 (6), S2—In1—S3 = 88.28 (6), C2—In2—S3 = 118.2 (3), C2—In2—S4 = 124.1 (3), S3—In2—S4 = 115.00 (7), C2—In2—S2 = 102.4 (2), S2—In2—S3 = 87.02 (6), S2—In2—S4 = 95.87 (6)°]. Bond lengths and angles are similar at each indium atom.
