Abstract

In 2-chloromethyl-2λ5-2,2′(3H,3′H)-spirobis[1,3,2-benzoxazaphosphole], which has been investigated by x-ray diffraction, the P atom has a distorted trigonal-bipyramidal coordination with O atoms in axial positions; the angle between the two planes of the 3H-1,3,2-benzoxazaphosphole fragments is 128.8°.
