The reactions of o-semiquinonediimine complexes M[o-(NH)(NPh)C6H4]2 (M = Ni (1) or Pt (2)) with carbonyl-containing iron and rhenium compounds were studied. The reactions of complexes 1 or 2 with Fc(CO)(5) afforded the Fe-2(CO)(6)[mu-(NH)(NPh)C6H4] complex (3) containing the bridging N-phenyl-o-phenylenediamide ligand in high yield. The reaction of the Re(CO)(2)(NO)Cl-2(thf) complex with complex 2 gave rise to the unusual mononuclear rhenium(III) complex, viz., Re(Ph)[sigma-eta (1)-o-(NH)(NHPh)C6H4](CO)(NO)Cl-2 (4), no changes in the geometry of N-phenyl-o-phenylenediamine bound to the Re(NO)(CO)(2)Cl-2 fragment being observed. The reaction of complex 2 with the Re(CO)(5)Cl complex, which has been preliminarily treated with silver triflate, afforded the heterometallic complex (CO)Pt[mu -N,N-o-(N)(NPh)C6H4](2)ReCl[(NH)(NPh)C6H4]. The structures of the resulting complexes were established by X-ray diffraction analysis.
