金属硫酸盐配合物具有显著的结构多样性。在铜(1)衍生物的情况下，这些范围从铜原子具有二和三配位的简单阴离子，通过环和笼，到复杂的簇。[']这类材料既可以作为它们自身的研究对象，也可以作为自然产生的含铜蛋白质的可能模型。在铜(1)配合物的情况下，结构的范围源于金属和硫原子采用各种配位模式的能力。铜(1)可以是二坐标、三坐标或四坐标，而硫代硫原子可以与一个、两个或三个金属原子结合。在已知的硫代酸酯中，最常见的结构单元是一个三坐标的铜原子与pc -桥接硫代酸酯键合。尽管现在已知的化学计量和结构范围很广，但对于简单的单硫酯配体，SR: Cu比从不小于1；金属原子间p2-硫酸酯桥接远比p3桥接常见，而对称p -桥接尚不清楚。我们现在报道了一种新的化合物，其中SR: Cu< OS，其中硫代酸盐
Metal thiolate complexes show remarkable diversity of structure. In the case of copper (1) derivatives, these range from simple anions with two-and three-coordination for the copper atom, through rings and cages, to complicated clusters.[’] Such materials are studied both in their own right and as possible models for naturally occurring copper-containing proteins. In the case of copper (1) complexes the range of structures arises from the ability of both the metal and sulfur atoms to adopt various coordination modes. Copper (1) can be two-, three-, or four-coordinate, while the thiolate sulfur atom can bind to one, two, or three metal atoms. The most common structural unit in the known thiolates is a three-coordinate copper atom bonded to pc,-bridging thiolates. Despite the wide range of stoichiometries and structures now known, the SR: Cu ratio is never less than 1 for simple monothiolate ligands; p2-thiolate bridging between metal atoms is far more common than p 3 bridging, while symmetrical p,-bridging is unknown. We now report a novel compound in which SR: Cu< OS, and in which the thiolate sul-
