Abstract
Raman data suggest that a crystallographically determined Cl 3CD⋯F2BF2- interaction in the solid-state structure of [Ru(CNBut)(CO)(η2-C 6-H4-2-CHO)(PPh3)2][BF 4]·2CDCl3 is an example of a blue-shifting bifurcated hydrogen bond. The ν(C-D) band blue-shifts 5 cm-1 to 2269 cm-1 compared to 2264 cm-1 for CDCl3 in the gas phase and 20 cm-1 from frozen CDCl3 at 2249 cm-1. A conventional interpretation of these band shifts would suggest that the CCl2 fragment of DCCl3 is a stronger hydrogen-bond acceptor than the BF2 fragment of a BF4 - group. © 2007 American Chemical Society.
