Abstract
- Distinct batches of orange (1a–e) and green crystals (2a–e) were isolated from the reactions of MoCl<subscript>5</subscript> with tetrahydropyran (thp), respectively at room temperature (in CH<subscript>2</subscript>Cl<subscript>2</subscript>) and at ca. 80 °C (in ClCH<subscript>2</subscript>CH<subscript>2</subscript>Cl). Crystals 2a–e are isomorphous to 1a–e and the IR spectra are almost superimposable. 1a–e were identified by X-ray studies as cis-MoCl<subscript>4</subscript>(thp)<subscript>2</subscript>, in agreement with previous findings. Careful refinement of the X-ray data of 2a–e by modeling one position as disordered between chlorine (minor component) and oxygen (major component) led to the conclusion that 2a–e consisted of a mixture of cis-MoCl<subscript>4</subscript>(thp)<subscript>2</subscript> and mer-MoOCl<subscript>3</subscript>(thp)<subscript>2</subscript>, the latter being largely prevalent.
