Abstract
Crystals ofbis-(1-methyl-3-o-chlorophenyltriazene 1-oxide)cobalt(II) have been subjected to X-ray analysis. They are in the orthorhombic space group P212121 with four molecules of C14Hx4N602ClzCo in a unit cell of dimensions a=19.035, b=13.287 and c=7.045 A. The heavy atom method was used. Refinement was carried out by the full-matrix least-squares method using 853 observed reflexions. The final R index is 0.077. Two ligands in the complex are in cis positions to each other and function as tridentate with O,N and C1 as coordinating atoms. The chlorine atoms which are also attached to the benzene rings were found to be very weakly coordinated to the cobalt ion completing a distorted octahedral coordination. The Co-C1 distance is 2.98/~. All other bond distances and angles are normal.
