TL;DR: In this paper, the perchlorate ion complexes have been studied and the metal-perchlorate bond has been termed as "semicoordination" and has been shown to be weak.
Abstract: Publisher Summary This chapter discusses the perchlorate ion complexes. Coordination of perchlorate to transition and nontransition metal ions has been well established, though in most of the cases the metal-perchlorate bond is rather weak and has been termed as “semicoordination”. The highly symmetrical perchlorate ion is a hard base and falls into the category of relatively nonpolarizable and noncoordinating anions such as BF 4 ˉ and PF 6 ˉ. Its ability to coordinate strongly to soft metal ions is therefore limited. When coordination does occur, the perchlorate group may be linked to a metal ion in a monodentate and/or bidentate manner through oxygen atoms; the latter linkage can be either chelating. X-ray crystal structure analysis has unequivocally established coordination of perchlorate in a number of perchlorate complexes.
