The title compound, C34H34, systematic name 9,9,9',9'-tetra-ethyl-2,2'-bi(9H-fluorene), crystallized with two crystallographically independent mol-ecules (A and B) in the asymmetric unit. These differ mainly in the orientation of the lateral ethyl chains: in mol-ecule A, they are both on the same side of the mol-ecule whereas in mol-ecule B, one di-ethyl-fluorene moiety has undergone a 180° rotation such that the two pairs of ethyl residues appear on opposite sides of the mol-ecule. The fluorene ...[more]
