The formation of molecular compounds in the reaction between [MgCl 2(THF) 2] and [MoCl 3O(THF) 2]. Crystal structure of [{MoCl 4O(THF)} 2Mg(THF) 4]·CH 2Cl 2

Abstract

The interaction of [MgCl 2(THF) 2] with [MoCl 3O(THF) 2] in 1:1 and 1:2 ratios in CH 2Cl 2 gave the paramagnetic complexes [(THF) 3Mg(μ-Cl) 3MoCl 2O] I and [{MOCl 4O(THF)} 2Mg(THF) 4]·CH 2Cl 2 II (THF, tetrahydrofuran). In complex I, the molybdenum and magnesium atoms are octahedrally surrounded by three bridging chlorine atoms and terminal oxo-oxygen and two chlorine atoms and by three THF molecules, respectively. Complex II consists of Mg 2+ ions coordinated by four THF molecules and two trans[MoCl 4O(THF)] − anions coordinated to an Mg atom by oxo O-atoms.
