B. Modec et al., The syntheses and crystal structures of two chromium(III) and molybdenum(III) coordination compounds with 4-ethylpyridine, J CHEM CRYS, 30(5), 2000, pp. 345-349
The structures of trichlorotris(4-ethylpyridine)chromium(III), [CrCl3(C7H9N
)(3)] (I), and trichlorotris(4-ethylpyridine)molybdenum(III), [MoCl3(C7H9N)
(3)] (II), consist of neutral molecules where three 4-ethylpyridine and thr
ee chloro ligands coordinate to the metal with a meridional configuration.
Compound I crystallizes in a trigonal space group P3(1) with a = 11.515(2)
Angstrom and c = 15.378(3) Angstrom. Compound II crystallizes in a monoclin
ic space group c 2/c with a = 24.200(3) Angstrom, b = 18.089(3) Angstrom, c
= 22.6004(7) Angstrom and beta = 106.7137(6)degrees.
