Abstract
Reaction of [Re(O)(CI){η 3 -(SCH 2 CH 2 ) 2 S}] with 3-amino-5-mercapto-1,2,4-triazole in 1: 2 molar proportion in acetonitrile gives rise to a red compound, [ReO{η 3 .(SCH 2 CH 2 ) 2 S}(C 2 H 3 N 4 S)] (1). Subsequent crystallisation of it from a 1: 1 mixture of acetonitrile and N,N-dimethylformamide (DMF) affords red crystals of 1.DMF· The X-ray structure shows that each molecule of the Re v complex is connected to another nearest neighbouring Re v complex via a DMF molecule with extensive hydrogen bonding. The complex displays a rare example of a 3D network involving all of the possible intermolecular hydrogen bonding and weak C-H...π interaction.
