interaction with phenol in the presence of trimethylphosphine leads to the compound trans-Re(OPh))4(PMe3)2, (C), while with lithium bis (trimethylsilyl)-amide a unique four-co-ordinate rhenium(V) compound, ReON(SiMe3)2}3, is obtained. The crystal and molecular structures of (A)–(C) have been determined by X-ray crystallography. Compound (A) is monoclinic, space group P21/n, a= 12.142(1), b= 15.369(1)
