title: π-π Dimerization of a mono(pyridyl-imine) platinum(II) chelate.
abstract: The cation of the title complex salt, chlorido{2,2-dimethyl-N-[(E)-1-(pyridin-2-yl)ethylidene]propane-1,3-diamine}platinum(II) tetrafluoridoborate, [PtCl(C(12)H(19)N(3))]BF(4), exhibits a nominally square-planar Pt(II) ion coordinated to a chloride ion [Pt-Cl = 2.3046 (9) Å] and three unique N-atom types, viz. pyridine, imine and amine, of the tridentate Schiff base ligand formed by the 1:1 condensation of 1-(pyridin-2-yl)ethanone and 2,2-dimethylpropane-1,3-diamine. The cations are π-stacked in inversion-related pairs (dimers), with a mean plane separation of 3.426 Å, an intradimer Pt···Pt separation of 5.0785 (6) Å and a lateral shift of 3.676 Å. The centroid (Cg) of the pyridine ring is positioned approximately over the Pt(II) ion of the neighbouring cation (Pt···Cg = 3.503 Å).
