This paper reports that diphenyldiselenide has been prepared by PhSeH using O_2 in air, and CdCl_2 as catalyst. This is a novel synthetic technology. The crystal structure and IR of diphenyldiselenide have been characterized. The title compound crystallizes in the space group P2_12_12_1, with a=0.56462nm, b=0.82883nm, c=2.41009nm; V=1.1276(7)nm^3, D_(c)=1.839 g·cm^(-3), Z=4, R=0.0259。
