| 中文摘要 | reactions of anhydrous lncl(3) (ln = nd, gd, dy, er, yb) with 2 equiv of licp' in thf afford the lanthanocene complexes of cp'(2)ln(mu-cl)(2)li(thf)(2) (cp' = eta(5)-t-buc5h4, ln = nd (1), gd (2), dy (3), er (4), yb (5); cp'= 1,3-eta(5)-t-bu2c5h3, ln = nd (6), gd (7), dy (8), er (9), yb (10)). the molecular structures of 7 and 8 were characterized by x-ray crystallographic analysis. in these complexes, two cp' ring centroids and two it-bridging chloride atoms around the lanthanide atoms form a distorted tetrahedron. the insertion of elemental chalcogen e (e = s, se) into li-c bonds of dilithium o-carborane in thf solution afforded dimers of dilithium. dichalcogenolate carboranes, [(thf)(3)lie2c2b10h10li(thf)](2) (e = s (12a), se (12b)), which were confirmed by a crystal structure analysis. reactions of cp'(2)ln(mu-cl)(2)li(thf)(2) (1-10) with 12a or 12b gave dinuclear complexes of the formula [li(thf)(4)](2)[cp'(2)lne(2)c(2)b(10)h(10)](2) (cp'= eta(5)-t-buc5h4, e = s, ln = nd (13a), gd (14a), dy (15a), er (16a), yb (17a); e = se, ln = nd (13b), gd (14b), dy (15b), er (16b), yb (17b); cp'= 1,3-eta(5)-t-bu2c5h3 e = s, ln = nd (18a), gd (19a), dy (20a), er (21a), yb (22a); e = se, ln = nd (18b), gd (19b), dy (20b), er (21b), yb (22b)). according to the x-ray structure analyses, the dianions of 13a and 13b contain two o-carborane dichalcogenolate bridges, and each cp'2ln fragment is attached to one terminal and two bridging chalcogen ligands. the central ln(2)e(2) four-membered ring is not planar, and the direct metal-metal interaction is absent. |
