Bis[μ-3,5-bis(pyridin-2-yl)pyrazolato]bis[(hexafluorophosphato)copper(II)]

Abstract

Key indicators: single-crystal X-ray study; T = 200 K; mean (C-C) = 0.003 Å; R factor = 0.027; wR factor = 0.074; data-to-parameter ratio = 14.9.The title dinuclear complex molecule, [Cu 2 (C 13 H 9 N 4 ) 2 (PF 6 ) 2 ], lies about an inversion center. The Cu II atom shows a squarepyramidal coordination geometry with the basal plane formed by four N atoms of the two bis-chelating 3,5-bis(pyridin-2-yl)pyrazolate ions and with one F atom of the hexafluorophosphate ion in the apical position. Molecules are stacked in a column along the a axis through C-HÁ Á ÁF hydrogen bonds. The columns are further linked by other C-HÁ Á ÁF hydrogen bonds, forming a three-dimensional network.
