摘要

J. Am. Chem. Sot. 1983, 105, 5507-5509 5507 and is consistent with the value of-2.3 A that Dahl et al. 7a9b have suggested for the arsenic-arsenic double bond. The bond angles at arsenic (99.9 (3) O at As (1); 93.6 (3)'at As (2)) are appreciably smaller than the bond angles at phosphorus in the diphosphenes 5 (108.5 (4)'av) 6 and 6 (102.8 (1) O), la reflecting both the tendency to increasing p character in the ligand bonds as group 5A in descended and ...
