Chromium(III) and Molybdenum(III) Complexes with Tetradentate Nitrogen Donor Macrocyclic Ligands

摘要

Chromium(III) and molybdenum(III) form complexes of genered composition [MLX_2]~X (M = Cr or Mo, L = 2,3,8,9-tetra-methyl-1,4,7,10-tetraazacyclododeca-1,3,7,9-tetraene (N_4), (TMM) and 2,3,8,9-tetraphenyl-6,12-dimethyl 1,4,7,10-tetraazacyclo-dodeca-1,3,7,9-tetraene (N_4), "(TPM) and (X = NCS~-, Cl~- and Br~-). These complexes have been synthesized by template method and isolated in solid state. They are characterized by elemental analysis, IR and electronic spectra, magnetic moments and molar conductance.
