SYNTHESIS AND CHARACTERIZATION OF RHENIUM PHOSPHINOTHIOLATE COMPLEXES- CRYSTAL AND MOLECULAR-STRUCTURES OF [HNET3][RE(P(C6H4S)(3))(2)], [REOCL(OP(C6H5)(2)(C6H4S))(P(C6H5)(2)(C6H4S))], [RE2O5(P(C6H5)(2)(C6H4S))(2)], AND [REOCL(OP(C6H5)(2)(2-SC6H3-3-SIME))(2)]

The reactions of ammonium perrhenate, HCl(aq), and the phosphinothiol ligands (2-HSC6H4)P(C6H4X)(2), where X = H or SH [abbreviated P-(SH)(x ) (x = 1, 3)], in alcohol have led to the isolation of a series of rhe nium complexes containing the {M(P-S-x)(2)} core, represented by [Re{P (C6H4S)(3)}{P(C6H4S)(2)(C6H4SH)}] (1), [ReOCl-{OP(C6H5)(2)(C6H4S)}{P(C 6H5)(2)(C6H4S)}] (3), and [ReOCl{OP(C6H5)(2)(2-SC6H3-3 -SiMe3)}(2)] (5 ). The reaction of 1 with NEt3 results in the formation of [HNEt3] [Re {P(C6H4S)(3)}2] (2) by deprotonation of a thiol ligand. The reaction o f ammonium perrhenate with P-(SH) also led to the isolation of the bin uclear species [ReOCl{OP-(C6H5)(2)(2-SC6H3-3 -SiMe3)}(2)] (4).
