双（环戊二烯基）镧系元素和卤化钇络合物是这些元素的有机金属化学中的基本前体。 2" 6 它们的合成对该领域至关重要，其结构参数为评估更复杂的系统提供了直接的基准。我们实验室最近对有机钇和有机镧系化学的研究已经制备出了三种卤化物配合物 (C5Me5) 2YCl (THF)(I)、(C5Me5) 2SmCl (THF)(II) 和 (C5Me5) 的 X 射线质量晶体。 2SmI (THF)(III) 的结构均已确定并在本文中进行了报道，因为它们是第一个进行结构表征的 (C5Me5) 2LnX (THF) 配合物（X=卤化物），因此它们为双（五甲基环-(1)(a) 大学的快速增长领域2" 46 提供了有用的基本结构数据。加利福尼亚州，(c) 阿拉巴马大学。
Bis (cyclopentadienyl) lanthanide and yttrium halide complexes are basic precursorsin the organometallic chemistry of these elements. 2" 6 Their synthesis is of fundamental importance to the field, and their structural parameters provide straightforward benchmarks upon which to evaluate more complex systems. Recent investigations of organoyttrium and organolanthanide chemistry in our laboratories have resulted in thepreparation of X-ray-quality crystals of the three halide complexes (C5Me5) 2YCl (THF)(I),(C5Me5) 2SmCl (THF)(II), and (C5Me5) 2SmI (THF)(III). The structures of each of these com-plexes have been determined and are reported herein. Sincethese are the first (C5Me5) 2LnX (THF) complexes (X= halide) to be structurally characterized, theyprovide useful, basic structural data in the rapidly growing area2" 46 of bis (pentamethylcyclo-(1)(a) Alfred P.
