title: Tetra-pyrazine-platinum(II) bis-(tetra-fluoro-borate) acetonitrile hemisolvate.
abstract: The improved synthesis and characterization of tetra-pyrazine-platinum(II) bis-(tetra-fluoro-borate) acetonitrile hemisolvate, [Pt(C(4)H(4)N(2))(4)](BF(4))(2)·0.5CH(3)CN, is reported. The unit cell contains a half equivalent of an acetonitrile solvent mol-ecule per tetra-pyrazine-platinum(II) ion. The coordination geometry of the Pt(II) ion is almost square-planar, with the Pt atom residing on an inversion center. The BF(4) (-) counter-anion, located at a general position, has an idealized tetra-hedral geometry and an acetonitrile solvent mol-ecule, the methyl group of which is disordered over two equal positions, sits on a twofold rotation axis.
