Hardcover RefComment: Written for scientists and researchers in the fields of chemistry and physics Abstract: This fourth subvolume presents data on the geometric parameters (internuclear distances, bond angles, dihedral angles of internal rotation etc) of free polyatomic molecules including free radicals and molecular ions. The survey on structure data consists of four subvolumes, each containing the geometric parameters determined in the gas phase either by an analysis of the rotational constants (and sometimes the vibrational constants) obtained from microwave, infrared, Raman, electronic and photoelectron spectroscopy or by an analysis of electron diffraction intensities. Most of the structures listed in the tables are for molecules in the electronic ground state, but structures for electronically excited states have also been included as far as they are available. In this fourth subvolume, the structure of molecules containing five to sixty carbon atoms is listed.

- 化学特性:二茂镍又称二环戊二烯合镍，为深绿色晶体，由于在分子轨道的反键轨道上有填充电子，致使其结构不稳定，遇空气和光缓慢分解，被氧化后变为橙黄色C10H10Ni+。熔点171～173℃；不溶于水，溶于乙醚、苯、四氢呋喃等大多数有机溶剂；有反磁性。与二茂铁一样具有夹心型结构,其中镍的氧化数为＋2。二茂镍十分活泼，在空气中迅速分解，在丙酮、乙醚、乙醇中分解。可由溴化镍与环戊二烯钠NaC5H5反应而制得二茂镍；可做燃料的抗震剂和催化剂；单环戊二烯镍和双环戊二烯基镍，可作为烃类氰代、取代衍生物的基本原料，烃类精炼催化剂、氢化催化剂、自由基聚合反应剂、硫化加速剂、燃料抗震剂，亦用于镀镍、制备高纯镍、炔烃聚合的催化剂等，本品有毒，吸入或皮肤接触都有害。 Ni(0)都是四配位四面体的配合物，最重要的是四羰基合镍〔Ni(CO)4〕，它是发现最早的金属羰基配合物，用于制造高纯镍。羰基镍有毒，使用时应避免吸入其烟气。使〔Ni (CO)4〕跟二茂镍(Ni(C5H5)2〕在80℃起反应可生成紫红色〔Ni(CO)2(C5H5)2〕，如果在高温下反应，就生成绿褐色〔Ni3(CO)2(C5H5)3〕。这些都是含有金属间键和羰基(CO)桥连的复杂化合物，用作制造多种有机镍化合物的原料。
