DOCUMENT TYPE: Journal CA Section: 75 (Crystallography and Liquid Crystals) Section cross-reference(s): 29 Tricyclopentadienylerbium and tricyclopentadienylthulium are orthorhombic, space group Pna21, with a 1972.1(3) 1999.1(3), b 1389.4(1) 1379.8(4), and c 862.4(3) 857.8(3) ?, and R 0.076 0.047, resp.; Z = 4 (2 mols./Z). At coordinates are given. The existence of coordinately well-satd. mols. contg. just 3 h5-C5H5 ligands permetal ion is confirmed. Individual mols. are aligned into chains by Van der Wells interactions. The structures show a marked contrast to those of their La and Pr homologs on the one hand, and with the structure of (C5H5)3Lu on the other. .
