Sodium [2-(mercaptomethylcarbonylamino)-N-(2-mercaptophenyl)ethanamide(4-)-[kappa]4S,N,N',S']oxorhenate(V) monohydrate

In the complex anion of the title compound, Na[Re(C10H8N2O2S2)O]·H2O, the Re atom adopts a square-pyramidal coordination, in which the Re=O bond is apical and the S,N,N,S-tetradentate ligand spans the four basal sites. The Na+ counter-ion is octahedrally surrounded by one S and five O atoms

Tetraphenylphosphonium [N-(2-aminophenyl)-2-(mercaptomethylcarbonylamino)ethanamido(4-)-[kappa]4S,N,N',N'']oxorhenate(V)

The title compound, (C24H20P)[Re(C10H9N3O2S)O], contains well separated square-pyramidal [OReL]- complex anions (L is the deprotonated N-(2-aminophenyl)-2-(mercaptomethylcarbonylamino)ethanamide ligand) and tetrahedral [(C6H5)4P]+ cations. In the anion, the Re=O bond is oriented along the apical direction and the four basal sites are occupied by one S- and three N-atom donors of the tetradentate L4- ligand
