Crystal structure of bis­(aceto­nitrile-κN)(4,4′-di-tert-butyl-2,2′-bi­pyridine-κ(2) N,N′)platinum(II) bis­(tetra­fluorido­borate) packing as head-to-head dimers

The crystal structure of a platinum(II) supra­molecular building block, [Pt(dbbpy)(NCCH(3))(2)](BF(4))(2) (dbbpy = 4,4′-di-tert-butyl-2,2′-bi­pyridine, C(18)H(24)N(2)) is an example of a rare head-to-head dimer, even with the bulky tert-butyl groups of the bi­pyridine. This packing motif still enables significant π–π inter­actions between two pyridyl groups, and may result from the close proximity of the tetra­fluorido­borate ions to the platinum(II) complexes, resulting in intra­molecular H⋯F distances between 2.156 and 2.573 Å.
