Structural Features of Mononuclear Dioxomolybdenum(VI) Chelates with Bidentate Chelate Substituted Salicylideneimines [MoO2(Lm)2] (m = 1–17)

详细

Some structural features of chelates with the general formula [MoO₂(L^m)₂] (I–XVIII), where L^m is a bidentate chelate (N, O) ligand representing a substituted salicylideneimine (m = 1–16), are considered. The trans positions to oxo ligands in complexes I–III and V–XVII are occupied by the neutral N atoms of ligands L^m, while the trans positions to O(oxo) ligands in complex IV are occupied by O(L⁴) acido atoms. Ligand L¹⁷ in the complex [MoO₂(L¹⁷)₂] (XVIII) is coordinated to the Mo atom via the O(L¹⁷) and O(L¹⁷-R²) oxygen atoms, R² = 6-Oh, of bidentate chelate (O, O) ligand L¹⁷. The N(L¹⁷) nitrogen atom is not coordinated to the metal atom.
