(isomer B) has cocrystallized with isomer A (12%). In two 14e compounds that contain isomer A, the Mo═C–C angles differ by 30–36°, consistent with a Mo. . .C–Hβ agostic interaction. Several of the complexes reported here react readily with ethylene, 1-decene, or cyclooctene to give the expected products, thus confirming their viability as initiators or intermediates in metathesis reactions.
