摘要：

The reaction of [(nC4H9)4N]2[Mo2O7] with BaC5O5 in acetonitrile yields red crystals of [(n C4H9)4N]2[MoO2(C5O5)2]. The compound crystallizes in the monoclinic space group C2/c with a=36.502(11), b=14.681(3), c=18.109(5) Å, β=93.84(1)°, V=9682.5(15) Å3, Dcalc=1.22 g cm-3 for Z=8. Structure solution and refinement based on 3593 reflections with Fo≥6σ(Fo) Mo Kα, λ= 0.71073 Å) converged at 0.0693. The structure of the anion consists of a mononuclear Mo(VI) center in ar distorted octahedral environment of the cis-oxo groups and the oxygen donors of two bidentate croconate ligands. The 1,2-chelating geometry of the croconate is unusual in that all previously structurally characterized examples of croconate coordination exhibit additional bonding to a second metal site via the oxygen donor in the 4 position. © 1990.
