Tetra--6-methylpyridin-2-olato-ditungsten toluene sesquisolvate

M. H. Chisholm, J. C. Gallucci and C. B. Hollandsworth

Abstract: The red title compound, [W₂(C₆H₆NO)₄]·1.5C₇H₈, contains isolated W₂(hmp)₄ molecules (hmp is 6-methylpyridin-2-olate) in which the W-W separation of 2.1617 (5) Å is consistent with the expected tungsten-tungsten quadruple bond. The complex molecule cocrystallizes with 1.5 molecules of toluene. One toluene molecule is disordered about a crystallographic inversion center, and the other, in a general position, is also disordered.
