Abstract
The X-ray diffraction study of new derivatives of perchlorate (9Н-xanthene-9-yl) and (4H-chromen-4-yl) triphenyl phosphonium is performed. It is demonstrated that the change in the molecular structure leading to a change in the degree of benzoannelation does not affect the phosphorus-carbon bond length. It is determined that perchlorate (2-phenyl-4Н-chromen-4-yl) triphenyl phosphonium сrystallizes as two polymorphs.
