Coligand effects on bonding mode. Synthesis and properties of (Diallylmalonato)platinum(II) complexes of P vs. N donating ligand

The reaction of cis-[Pt(II)(OH)2A2] (A = triethylphosphine (PEt3); A2 = tetrahydro-4H-pyran-4,4-dimethanamine (hpda)) with diallylmalonic acid in aqueous solution affords cis-[Pt(dam)A2] (dam = diallylmalonate). The bonding mode of the dam is dependent upon the donation effect of the phosphine vs the nitrogen coligand. The crystal structure of cis- [Pt(dam)(PEt3)2] (C21H40O4P2Pt·H2O: monoclinic P21/c, a = 13.918(2), b = 12.464(1), c = 15.737(1) A, β = 107.097(8)°, V = 2609.4(4) A3, Z = 4, R = 0.033) discloses that the dam is bonded to the platinum atom in a (χ2 O3)-mode (Pt-O = 2.057(4), 2.061(4) A) with two phosphine ligands in the cis position. In contrast, for cis-[Pt(dam)(hpda)] (C16H16N2O5Pt·4.5H2O: monoclinic C2/c, a = 28.250(3), b = 11.169(1), c = 13.368(4) A, β = 94.16(1)°, V = 4207(1) A3, Z = 8, R = 0.0293), the dam ligand is chelated to the platinum(II) ion in a (χO, η2-C,C)-mode (Pt- O = 2.004(4) A; Pt-C = 2.089(6), 2.101(6) A) in the solid state. cis- [Pt(χ2O3-dam)(PEt3)2] easily reacts with KBr pellet matrix for IR measurements while cis-[Pt(χO, η2-C,C-dam)(hpda)] is inert in the pellet. In solution, however, the structure of cis-[Pt(χO3-dam)(PEt3)2] is locked, whereas cis-[Pt(χO, η2-C,C-dam)(hpda)] can be isomerized to cis- [Pt(χ2O3-dam)(hpda)].
