关于水合铜离子的配位,在国内教科书中提法很多。有的认为水合铜离子铜的配位数是4,空间构型是平面正方形;有的认为水合铜离子中铜的配位数是6,空间构型是畸变八面体或四角形畸变;有的在同一本书中,就有不同的提法。这给教学带来不便。本文试图从如下两个方面给予讨论。 Coordination of hydrated copper ions, many references in the domestic textbooks. Some believe that the hydration of copper ion copper coordination number is 4, the space configuration is a square plane; some think that copper hydration of copper coordination number is 6, the spatial configuration is distorted octahedron or quadrilateral distortion; some in In the same book, there are different references. This brings inconvenience to teaching. This article attempts to discuss the following two aspects.
