“…The GeSe2C6 part of the molecule is planar with the highTst deviations from the least-squares plane of 0.02 A observed for Se atoms. Such a geometry is quite different from that found in the complexes of do zirconocenes with 0-Z,-Z2-C6H4 ligands (Z, = Se, (Te, S); Z2 = Se, (S, Te)) [30,45], where the dihedral angles between the ZlZ2 and Z2C6 planes are 54-56'. It is worth noting that, in the ditelluraphenylene complex of platinum, Pt(Te2C6H4)(PPh3)2, the PtTe, and TezC6 moieties are essentially coplanar [46].…”
