Crystal and molecular structure of 2,3,6-triphenylarsenin
Abstract
Crystals of the title compound are monoclinic, space group C2/c, with a= 31·768, b= 10·456, c= 10·543 Å, β= 94·58°, Z= 8. Diffractometer data for 1648 planes were used to solve the structure by Patterson methods and were refined by least squares to a final R of 0·085. The arsenin ring shows no significant departures from mm2 (C2v) symmetry and exhibits only two different bond lengths: As–C 1·872(14) and C–C 1·405(20)Å.
