High-resolution one- and two-dimensional solid-state CP/MAS spectra of microcrystalline bent metallocene complexes of the type ({eta}{sup 5}-{sup R}Cp){sub 2}ZrL{sub 2} have been obtained at various temperatures (L = Cl, R = H (1), Me (2), Et (3), {sup t}Bu (4); L{sub 2} = s-cis-{eta}{sup 4}-C{sub 4}H{sub 6}, R = {sup t}Bu (8); L{sub 2} = s-cis-{eta}{sup 4}-C{sub 4}H{sub 6}, R = 1,1-dimethylpentyl (9); L{sub 2} = s-cis-{eta}{sup 4}-C{sub 4}H{sub 5}Me, R = {sup t}Bu (10)). Complexes 1-4 possess C{sub 2} molecular symmetry, while the overall symmetry of complexes 5 and 6 is close to C{sub s}. In 7-9 there is no element of symmetry, and 10 yields diastereoisomers (95:5).
