metadata.value: One of two PtIV-activated propanenitriles in trans-[PtCl4(EtCN)2] is involved in platinum(IV)-mediated
  nitrile–imine coupling with the platinum(II)-based metallacycles [PtCl2{NHvC(NR2)N(Ph)C(vNH)N(Ph)-
  C(NR2)vNH}] [R2 = Me2 (1a), C5H10 (1b)] yielding diplatinum products, whose structures depend on molar
  ratios between the reactants. At a 1 : 1 ratio, the mixed-valence platinum(II)/platinum(IV) species
  [PtCl4{NHvC(NR2)N(Ph)C{v[(N(Et)CvNH)PtCl2(EtCN)]}N(Ph)C(NR2)vNH}] [R2 = Me2 (2a), (CH2)5 (2b)]
  were generated, whereas at a 1 : 2 ratio the dinuclear platinum(II)/platinum(II) complexes [PtCl2{NHv
  C(NR2)N(Ph)C{v[(N(Et)CvNH)PtCl2(EtCN)]}N(Ph)C(NR2)vNH}] [R2 = Me2 (3a), (CH2)5 (3b)] were obtained.
  In contrast to the nitrile–imine coupling observed for the platinum(IV) dinitrile complex, the reaction
  between the platinum(II) congener trans-[PtCl2(EtCN)2] and any one of 1a,b gives exclusively the substituted
  dimetallic platinum(II)/platinum(II) products [PtCl2{NHvC(NR2)N(Ph)C{v[(NH)PtCl2(EtCN)]}N(Ph)-
  C(NR2)vNH}] [R2 = Me2 (6a), (CH2)5 (6b)] featuring platinum-containing guanidine 1 as one of the ligands.
  Complexes 2a,b, 3a,b, and 6a,b were characterized by elemental analyses (C, H, N), HRESI-MS, IR,
  1H NMR spectroscopy, and DTA/TG. The molecular and crystal structure of 2a·2CDCl3 was additionally
  studied by single-crystal X-ray diffraction. Complexes 2a,b undergo further redox transformation in solutions,
  and single crystals of [PtCl2{NHvC(NMe2)N(Ph)C{v[(N(Et)CvNH)PtCl2(MeCN)]}N(Ph)C(NMe2)v
  NH}]·2CH2Cl2 (3’a·2CH2Cl2) were obtained from 2a in a CH2Cl2–MeCN–C2H4Cl2 mixture and studied by
  X-ray crystallography. The driving forces for the generation of diplatinum products 2 and 3 were elucidated
  based on a quantum-chemical study.
