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 π-π 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.

Keywords: crystal structure; platinum(II); supramolecular.
