摘要

A series of mercury dithioether coordination polymers were synthesized from mercury dihalides and rigid xylyl dithioethers containing methyl, t-butyl, and benzyl pendant groups (ligands 3a-c). The resulting coordination polymers were examined by X-ray crystallography. Changes in sterics surrounding mercury result in structures ranging from one-dimensional polymers (e.g., (3a?HgI _2) _∞, (3b?Hg _2Cl _4) _∞, (3b?HgBr _2) _∞) to two-dimensional sheets (e.g., (3c?HgCl _2) _∞) and three-dimensional extended networks (e.g., [(3c) _2(HgBr _2) _3] _∞) from crystallizations which were conducted under identical conditions with the same 1:1 stoichiometry. Bridging mercury-halide bonds were found to play a surprisingly large role in governing the final structures.
