Abstract
The reaction of AgNO3 with trans- and cis-[Pt(NH3)2(NHCOMe-N)2]1 and 2 yielded the heteronuclear polymeric complexes cis-[(NH3)2Pt(NHCOMe)2Ag]NO3·4H2O 3 and trans-[(NH3)2Pt(NHCOMe)2Ag]NO3·1.5H2O 4. Complexes 3 and 4 have been studied in solution and characterised by X-ray analysis: 3, tetragonal, space group I41/a, a=b= 15.874(2), c= 22.918(5)Å, Z= 16; 4, triclinic, space group P, a= 7.143(3), b= 8.416(5), c= 11.544(6)Å, α= 78.61(4), β= 89.67(4), γ= 83.79(4)°, Z= 2. The Pt ⋯ Ag distances are 2.897(1) and 2.903(1)(3) and 2.925(2) and 2.919(2)Å(4). Possible metal–metal bonding interactions are discussed.
