title: [(1R,2R)-1,2-diaminocyclohexane-kappa(2)N,N'](alpha-diimine-kappa(2)N,N')platinum(II) bis(hexafluorophosphate), where alpha-diimine is 2,2'-bipyridine and 1,10-phenanthroline.
abstract: The title Pt(II) complexes, viz. (2,2'-bipyridine-kappa(2)N,N')[(1R,2R)-1,2-diaminocyclohexane-kappa(2)N,N']platinum(II) bis(hexafluorophosphate), [Pt(C(6)H(14)N(2))(C(10)H(8)N(2))](PF(6))(2), and [(1R,2R)-1,2-diaminocyclohexane-kappa(2)N,N'](1,10-phenanthroline-kappa(2)N,N')platinum(II) bis(hexafluorophosphate), [Pt(C(6)H(14)N(2))(C(12)H(8)N(2))](PF(6))(2), containing an aromatic alpha-diimine and a non-planar diaminocyclohexane, both form a ladder-type structure, which is constructed via loose pi-pi stacking on the alpha-diimine ligands and hydrogen bonding between the cyclic amines and the counter-anions. In the former compound, there are two independent complex cations, both of which have a twofold axis through the Pt atom.
