Dichloro(propane-1,3-diamine-²N,N')platinum(II), dichloro(propane-1,3-diamine-²N,N')palladium(II) and -4,9-diazadodecane-1,12-diamine-²N¹,N⁴:²N⁹,N¹²-bis[dichloroplatinum(II)]

Abstract: In the title compounds, [PtCl₂(C₃H₁₀N₂)], (I), [PdCl₂(C₃H₁₀N₂)], (II), and [Pt₂Cl₄(C₁₀H₂₆N₄)], (III), each metal atom lies in a distorted cis-square coordination geometry. Compounds (I) and (II) are isostructural, and each complex has a mirror plane through the metal atom and the middle C atom of the propane-1,3-diamine ligand. In (III), the binuclear complex [Pt₂Cl₄(spn)] has an inversion center at the middle of the 4,9-diazadodecane-1,12-diamine (spermine, spn) ligand. The six-membered chelate rings in (III) adopt a chair form, which is unsymmetrical and less flattened than those in (I) and (II). In all three crystal structures, there are intermolecular N-HCl hydrogen bonds.

Formula: [PtCl₂(C₃H₁₀N₂)], [PdCl₂(C₃H₁₀N₂)] and [Pt₂Cl₄(C₁₀H₂₆N₄)]
