Abstract

Abstract: The reactions of CrCl2 with two N-heterocyclic carbenes (NHC) have afforded the complexes, trans-[CrCl2(NHC)2] (NHC = :C N(C6H3Pr2i-2,6)C(H) 21 or :C N(Pri)C(Me) 22). The cell parameters of the compounds are 1: P212121, a = 12.9445(4), b = 20.7364(5), c = 21.2841(6); 2: Pca21, a = 21.7583(14), b = 9.9465(8), c = 11.4414(9). The crystal structures of the complexes are the first for NHC adducts of CrCl2, and both exhibit square planar chromium centers.
