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-H center dot center dot center dot Cl hydrogen bonds.
