Abstract

Reactions of Mo2 (O2CCH3)(DAniF) 3, DAniF= N, N'-di-p-anisylformamidinate, with oxamidate dianions [ArNC (O) C (O) NAr] 2-, Ar= C6H5 and p-anisyl, give pairs of isomeric compounds where the [Mo2] units are bridged by the oxamidate anions. For the α isomers, the CC unit of the dianion is nearly perpendicular to the Mo-Mo bonds, and these are essentially perpendicular to each other. For the β isomers, the corresponding CC unit and ...
