Crystal structure of bis-(aceto-nitrile-?N)(4,4'-di-tert-butyl-2,2'-bi-pyridine-?2N,N')platinum(II) bis-(tetra-fluorido-borate) packing as head-to-head dimers.

ABSTRACT: The crystal structure of a platinum(II) supra-molecular building block, [Pt(dbbpy)(NCCH3)2](BF4)2 (dbbpy = 4,4'-di-tert-butyl-2,2'-bi-pyridine, C18H24N2) is an example of a rare head-to-head dimer, even with the bulky tert-butyl groups of the bi-pyridine. This packing motif still enables significant ?-? inter-actions between two pyridyl groups, and may result from the close proximity of the tetra-fluorido-borate ions to the platinum(II) complexes, resulting in intra-molecular H?F distances between 2.156 and 2.573?Å.
