H. Gailus et al., A ROUTE TO ETA(2)-ALKYNE COMPLEXES OF VANADIUM(I) - CRYSTAL-STRUCTUREOF TRANS-[IV(CO)(2)(PME(2)PH)(2)(2-BUTYNE)], Journal of organometallic chemistry, 465(1-2), 1994, pp. 181-185
The reaction between [V(CO)(6)](-), halogens, phosphines and alkynes y
ields the complexes trans-[HaIV(CO)(2)(PR(3))(2)(alkyne)], which have
been characterized by IR and multinuclear NMR spectroscopy. The struct
ure of the title compound has been determined by a single crystal X-di
ffraction study.
