Bis(3,5-dimethyl-1H-pyrazole-jN 2 )- silver(I) hexafluoridoantimonate Devyn Crawford, Anthony K. Hofer, Kate L. Edler and Gregory M. Ferrence* CB 4160, Department of Chemistry, Illinois State University, Normal, IL 61790, USA Correspondence e-mail: ferrence@illinoisState.edu Received 17 February 2011; accepted 21 March 2011 Key indicators: single-crystal X-ray study; T = 100 K; mean (C–C) = 0.009 A ˚ ; R factor = 0.042; wR factor = 0.138; data-to-parameter ratio = 24.1. The title compound, [Ag(C 5 H 8 N 2 ) 2 ]SbF 6 , contains an Ag + cation almost linearly bonded to two N atoms of dimethylpyr- azole ligands [N—Ag—N = 176.54 (18) ]. The structure exhibits hydrogen bonding between the two dimethylpyrazole H atoms and two F atoms of one hexafluoridoantimonate anion. Three relatively short AgF contacts [2.869 (6), 2.920 (7), and 3.094 (7) A ˚ ] exist between the cation and three different SbF 6 anions. The crystal used for data collection was found to be twinned by non-merohedry, with the two components being related by a 180 rotation around the real or reciprocal a axis. Integration resulted in 11.2% of the total peaks being assigned to component 1, 11.2% to component 2, and 77.6% to both components.
