Racemic tricarbonyl(eta 6-7-methoxyflavan)chromium(0)
(2010) In Acta Crystallographica Section E: Structure Reports Online 66. p.459-907- Abstract
- In the title compound [systematic name: tricarbonyl(eta 6-7-methoxy-2-phenyl-3,4-dihydro-2H-1-benzopyran)chromium(0)], [Cr(C16H16O2)(CO)(3)], the Cr(CO)(3) unit is coordinated by the phenylene ring of the flavan ligand, exhibiting a three-legged piano-stool conformation, with a point to plane distance of 1.750 (1) A. The phenyl ring is twisted away from the fused ring system by 36.49 (5)degrees (r.m.s. deviation = 0.027 A; fitted atoms are the C-6 ring and the attached fused-ring C and O atoms). The dihydropyran ring displays a distorted envelope configuration by displacement of the phenyl-bearing and the adjacent ring C atoms from the fused-ring system plane by 0.356 (2) and 0.402 (2) A, respectively.
