Diphenylantimony(III) and bis(2,6-dimethylphenyl)antimony(III) tiocyanates have been prepared by metathesis reactions between the appropriate diarylantimony(III) halide and potassium thiocyanate in acetonitrile solution.The second compound was also obtained by thermal decomposition of tris(2,6-dimethylphenyl)antimony(V) dithiocyanate.Crystal structure determinations showed that in SbPh2(NCS) the thiocyanate group bridges between antimony centres to give an infinite polymer, while the 2,6-dimethyl-substituted analogue is an N-bonded monomer.The diphenylantimony structure is probably unique in that the asymmetric unit consists of three formula units and, although each thiocyanate group is bridging, two are primarily N-bonded while the third is primarily S-bonded.Angles at the bridging nitrogens are large (150.4-174.9 deg) while those at sulfur are close to 90 deg (85.7-98.6 deg).These in conjunction with the presence of thiocyanate groups in the axial positions of pseudo-trigonal-bipyramidal arrangements about antimony lead to a curious 'triangular spiral' structure for the polymeric chains.
