Abstract

Specific features of the structures of five various complexes [Y(Me3tach)Cl3(THF)2] (I), [Y(Me3tach)2Cl3] (II), [Y(Me3tach)Cl2(μ-Cl)2YCl2(THF)3] (III), [Y(Me3tach)Cl3(THF)]2 (IV), and [Y(Me3tach)2Cl2]+[Y(Me3tach)Cl4]– (V) formed via the reaction of yttrium chloride tetrahydrofuranate with 1,3,5-trimethyl-1,3,5-triazacyclohexane (Me3tach) are compared. The molecular structures of newly synthesized complexes IV and V are determined by X-ray diffraction (XRD) (CIF files CCDC nos. 2484944 and 2484945, respectively). All complexes, except for complex V, demonstrate similar metal–ligand distances with a correction to the difference in coordination numbers regardless of the structure of the complex and metal to ligand ratio for both mono- and binuclear complexes.
