摘要：

A series of cocrystals of an organometallic tungsten complex with organic small molecules has been prepared and studied by single-crystal X-ray diffraction. Comparison of the five structures thus obtained allowed the measurement of the effects of the crystal environment on the molecular structure under investigation. Not only 'soft' torsional degrees of freedom but also bond angles, the point symmetry, and other geometrical features of the reference molecule have been found to vary significantly. It is concluded that parameters commonly ascribed to the molecular structure may in reality depend on intermolecular interactions.
