Abstract

The crystal structure of the title compound, [Cr(C8H8NO)3], is isotypic with the vanadium(III) analogue. The asymmetric unit consists of one Cr(3+) cation and three N-methyl-salicylaldiminate anions. The metal cation is octa-hedrally coordinated by three N,O-chelating N-methyl-salicylaldiminate ligands, leading to discrete and neutral complexes. In the crystal, neighbouring complexes are linked via C-H⋯O hydrogen-bonding inter-actions into chains propagating parallel to the c axis.

Keywords: N-methylsalicylaldiminate; chromium(III); crystal structure; hydrogen bonding.
