Two molybdenum pentacarbonyl complexes with electroneutral phosphane ligands: [bis(morpholin-4-yl)(pentafluoroethyl)phosphane-κP]pentacarbonylmolybdenum(0) and pentacarbonyl[(pentafluoroethyl)bis(piperidin-1-yl)phosphane-κP]molybdenum(0).

The crystal structures of the title compounds, [Mo{(C4H8NO)2P(C2F5)}(CO)5], (1a), and [Mo{(C5H10N)2P(C2F5)}(CO)5], (2a), were determined as part of a larger project that focuses on the synthesis and coordination chemistry of phosphane ligands possessing moderate (electroneutral, i.e. neither electron-rich nor electron-deficient) electronic characteristics.

Ogilvie's syndrome developing after ethanol ablation of renal cell carcinoma.

Urological procedures frequently are implicated as a cause of Ogilvie's syndrome. We report the first case of Ogilvie's syndrome following ethanol ablation of a renal cell carcinoma. The urologist must be alert to the development of this complication.
