✦ Synopsis

The reaction of the edge-bridged open zirconocene, Zr(6,6-dmch) 2 (PMe 3 ) 2 (dmch = dimethylcyclohexadienyl) with two equivalents of PhC 2 SiMe 3 leads to a 5 + 2 + 2 ring construction, resulting in a 4.3.1 bicyclodecadienyl skeleton. The resulting complex, with g 3 -allyl, g 4 -diene, and g 5 -dienyl coordination, has a formal 16 electron configuration, and contains close contacts between the metal center and two lengthened C-C bonds, indicative of weak agostic interactions.
