Abstract
Tricarbonylchromium-o-toluidine crystallises in the monoclinic system, space group C2/c, with eight molecules of C10H9CrNO3 in a cell of dimensions a= 19·25, b= 8·32, c= 13·80 Å, β= 170° 0′. After Fourier and least-squares refinement of the atomic parameters, the final discrepancy factor is 14·4% over 1448 independent reflexions. The tricarbonylchromium-o-toluidine molecule adopts the eclipsed configuration in which the carbonyl–chromium vectors point closely towards the benzene carbon atoms which are ortho and para to the amino substituent. The amino group participates in NHO hydrogen bonds of 3·17 and 3·21 Å with oxygen atoms of neighbouring molecules.Keywords
