An exceedingly short quadruple bond involving tungsten and the enigma of heteronuclear metal-metal bonds with multiple bond character

Crystals of MoW(O/sub 2/CC(CH/sub 3/)/sub 3/)/sub 4/ suitable for X-ray crystallographic examination were obtained after slow recrystallization from acetonitrile. Structure was determined to be triclinic with space group P anti 1 Z = 1, a = 10.866(4), b = 5.774(1), c = 11.263(2) A; ..cap alpha.. = 9...

Zusammenfassung:	Crystals of MoW(O/sub 2/CC(CH/sub 3/)/sub 3/)/sub 4/ suitable for X-ray crystallographic examination were obtained after slow recrystallization from acetonitrile. Structure was determined to be triclinic with space group P anti 1 Z = 1, a = 10.866(4), b = 5.774(1), c = 11.263(2) A; ..cap alpha.. = 92.81(2), ..beta.. = 109.63(2), ..gamma.. = 89.61(2)/sup 0/. The bond distance for molybdenum-tungsten was calculated to be an extremely short 2.080(1)A. Molecular structure is shown.
