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-Si

摘要

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 rhenium 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(C6H5)(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 of ammonium perrhenate with P-(SH) also led to the isolation of the binuclear species [ReOCl{OP-(C6H5)(2)(2-SC6H3-3 -SiMe3)}(2)] (4).
