title: A head-to-head isomer of di-mu-pivalamidato-kappa4N,O-bis[(1,10-phenanthroline-kappa2N,N')platinum(II)] dinitrate dihydrate.
abstract: In the title compound, [Pt(2)(C(5)H(10)NO)(2)(C(12)H(8)N(2))(2)](NO(3))(2)*-2H(2)O, the intradimer Pt-Pt distance is relatively short [2.8489 (17) A], which must be due to the strong intramolecular pi-pi-stacking interactions between the phenanthroline moieties. The dimers stack along the c axis, forming one-dimensional columns in which very intriguing d-d, pi-pi and d-pi interactions exist. Although the dimer-dimer Pt...Pt distances are very long [4.340 (2) and 4.231 (2) A], some short interdimer Pt...C contacts leading to strong interdimer associations are found [3.325 (19) and 3.402 (19) A].
