Crystal chemistry of compounds containing mercury in low oxidation states
Abstract
The published data are surveyed and a comparative crystal-chemical analysis is presented for the structures of compounds containing mercury in low oxidation states as cluster Hgn groups with covalent Hg–Hg bonds. The geometry of compounds with Hg–Hg and Hg–X bonds (X = O, S, Se, N or Hal) is analysed and the types of coordination of mercury ions, the packing modes and the relationships between structural units are described. The crystallographic and crystal-chemical data for mercury compounds are given. The bibliography includes 124 references.
