The reactions of HRh(CO)L3 (L=PPh3, P(OPh) 3) complexes with AgY (Y=BF4-, CF 3SO3-, PF6-) lead to [Rh(CO)(PPh3)2(H2O)]Y and [Rh(CO)(P(OPh) 3)3]Y compounds. The solvolysis of [Rh(CO)(PPh 3)2(H2O)]PF6 in ethanol produced a crystalline trans-[Rh(CO)(PPh3)2(OPOF2)] complex containing distorted square-planar rhodium center. The different arrangement of OPOF2- ligands found in two crystallographically independent molecules is connected with the presence of intra- and intermolecular C-H...O hydrogen bonds involving both oxygen atoms of each OPOF2- anion. The reaction of [Rh(CO)(P(OPh) 3)3]Y (Y=BF4-, PF6 -) in solution with CO leads to [Rh(CO)2(P(OPh) 3)3]Y and with P(OPh)3 to [Rh(P(OPh) 3)4]Y complexes. The [Rh(P(OPh)3) 4]PF6 complex was also obtained as a final reaction product of HRh(P(OPh)3)4 with AgPF6.
