Tetrakis(acetonitrile-κN)lithium hexafluoridophosphate acetonitrile monosolvate

Abstract

In the title compound, [Li(CH 3CN) 4]PF 6·CH 3CN, the asymmetric unit consists of three independent tetra-hedral [Li(CH 3CN) 4] + cations, three uncoordinated PF 6- anions and three uncoordinated CH 3CN solvent molecules. The three anions are disordered over two sites through a rotation along one of the F - P - F axes. The relative occupancies of the two sites for the F atoms are 0.643 (16):0.357 (16), 0.677 (10):0.323 (10) and 0.723 (13):0.277 (13). The crystal used was a racemic twin, with approximately equal twin components.
