Molecular and Intracomplex Dioxomolybdenum(VI) Compounds with Substituted R1-Salycilidene-N-methylimines (HL): Crystal Structure of Three [MoO2(L)2] Complexes (R1 = H, 5-Br, 5-Cl)

Abstract

The synthesis and IR spectroscopic and X-ray diffraction studies of three [MoO₂(Lⁿ)₂] complexes with n = 1 (R = H, repeatedly) (I), n = 4 (R = Br) (II), and n = 3 (R = Cl) (III) have been performed. The molybdenum atoms in the structures of complexes I–III have a typical octahedral coordination with dioxo ligands in cis-positions, atoms N(Lⁿ) in trans-positions to О(oxo), and atoms О(Lⁿ) in cis-positions to oxo ligands. Ligands Lⁿ are bidentate chelate (N, O).
