ChemInform Abstract: Mo2O3Cl4(Pyridine)4·CH2Cl2. Synthesis, IR Spectrum, and Crystal Structure.

Abstract

Reduction of MoO2Cl2(Py)2 with PPh3 in toluene (20 °C, 2 h) and recrystallization from CH2Cl2 yields the title complex (I) in quantitative yield.

Syntheses and a Solid State Structure of a Dinuclear Molybdenum(V) Complex with Pyridine

“…The extent to which the trans influence is expressed within a certain complex differs from one case to another. [{MoOCl 2 (Py) 2 } 2 O], another dinuclear molybdenum(V) complex, with a pair of pyridine ligands being trans to each other displays Mo−N bonds with lengths of 2.169(5)−2.209(5) Å [19]. Their length may be explained in terms of a smaller trans influence of pyridine as compared to that of a bridging oxide in 1 and 2 .…”
