Abstract

The metal atom of the Cr(CO)(3) unit of the title compound, [Cr(C(17)H(14)O(4))(CO)(3)], is coordinated to the methoxy-phenyl ring of the isoflavone ligand; the Cr(CO)(3) unit exhibits a three-legged piano-stool conformation. The aromatic ring of the methoxy-phenyl group is twisted by 42.49 (9)° with respect to the γ-pyrone ring. In the fused-ring, the dihedral angle between the phenyl-ene and γ-pyrone rings is 3.08 (13)°.

摘要

标题化合物[Cr(C₁₇H₁₄O₄)(CO)₃]中Cr(CO)₃单元的金属原子与异黄酮配体的甲氧基苯环配位；Cr(CO)₃单元呈现出三脚钢琴凳构象。甲氧基苯基的芳环相对于γ-吡喃酮环扭转了42.49 (9)°。在稠环中，亚苯基环和γ-吡喃酮环之间的二面角为3.08 (13)°。
