Reaction of Mo 2(O 2CME) 2Cl 2(dppe) with pyridine; structural characterizations of the products of Mo 2Cl 2(OAc) 2Py 2 and MoOCl 2(dppe)(Py)

Abstract

By layering a CH 2Cl 2/pyridine solution of Mo 2Cl 2(OAc) 2(dppe) with n-hexane, two different kinds of crystals were obtained, both of which were characterized by X-ray crystallography. Crystal data for Mo 2Cl 2(OAc) 2Py 2 ( 1): P 1 , a=11.979(2), b=13.977(3), c=9.036(1) Å, α=103.15(1), β=94.46(1), γ=115.12(1)°, V=1307.5(4) Å 3, Z=2. Final residuals for 1: R=0.0493, R w=0.0660. Crystal data for MoOCl 2(dppe)(Py) ( 2): P2 1/ c, a=11.480(2), b=17.854(2), c=15.693(2) Å, β=115.51(1)°, V=2982.3(7) Å 3, Z=4. Final residuals for 2: R=0.0458, R w=0.0769. The molecules of 1 were found to be linked by two ClMo bridges (3.018 and 3.082 Å) into infinite chains.
