Ke. Duplooy et al., COORDINATION PROPERTIES OF NOVEL TRIDENTATE CYCLOPENTADIENYL LIGANDS IN TITANIUM AND ZIRCONIUM COMPLEXES, Organometallics, 14(7), 1995, pp. 3129-3131
Tridentate-linked amido-cyclopentadienyl ligands C(5)Me(4)SiMe(2)NCH(2
)R with a neutral donor site R (R = CH(2)OMe CH(2)NMe(2), CH=CH2) have
been. synthesized and coordinated at tetravalent titanium and zirconi
um centers. The molecular structure of Zr(eta(5):eta(1): eta(1)-C(5)Me
(4)SiMe(2)NCH(2)CH(2)NMe(2))Cl-2 (4b) was determined by a single-cryst
al X-ray structural analysis, revealing an unusual trigonal-bipyramida
l zirconium center with the CH(2)CH(2)NMe(2) moiety interacting with t
he zirconium center.
