要旨:
A novel supramolecular assembly [Hg6As4][YbBr6]Br has been prepared and its structure determined. It crystallizes in a cubic space group equation image, a = 12.362(1) Å, with Z = 4. The title compound is a bi-compartmental supramolecular architecture that is built of a three-dimensional [Hg6As4]4+ cationic framework trapping two types of guest anions, [YbBr6]3− and Br−, in a chessboard-like order. [Hg6As4][YbBr6]Br is a Curie-Weiss paramagnet with a magnetic moment of 4.47 μB, which reflects the localized character of the 4f13 electrons of Yb. Thus, the whole assembly behaves as a magnetically dilute compound.
