potentially wide applicability is described for the synthesis of previously unreported tris(heteroleptic) [Cr(diimine) 3 ] 3+ complexes. The synthetic scheme involves the sequential addition of three different diimine ligands, and employs CrCl 3 · 6H 2 O as the initial Cr(III) reagent. The synthesis and characterization of the complexes [Cr(TMP)(phen)(diimine′)] 3+ are reported (where TMP = 3,4,7,8-tetramethyl-1

The crystalstructure of the least-soluble isomer of trichloro(dimethylformamide)(1,10-phenanthroline)chromium(III) has been determined from photographic data collected about the c crystallographic axis. The monoclinic crystals have space group P21, with Z= 2, unit-cell dimensions a= 9.77 ± 0.02, b= 13.19 ± 0.04, c= 6.66 ± 0.02 Å, β= 104.7 ± 0.2°. Parameters for non-hydrogen atoms were refined by least-squares
