摘要：

An extended one-dimensional chain-type coordination polymer, [Rh-2(piv)(4)(tpy)](n) (1; piv = pivalate, tpy = 2,2':6',2 ''-terpyridine), has been synthesized and characterized by single-crystal and powder X-ray diffraction analyses, elemental analysis, IR spectrosopy, thermogravimetric analysis, UV/Vis diffuse reflectance spectroscopy, and magnetic measurements at 300 K. This complex shows unique repeatable self-assembly and disassembly transformation properties. Polymer 1 readily decomposed to its constituent building blocks, that is, [Rh-2(piv)(4)] and tpy, in organic solvents at 300 K, but the disassembly product of 1 readily re-self-assembled to give 1 as a crystalline product in aqueous ethanol solution at 373 K. In addition, 1 was obtained as a crystalline powder by a water-assisted mechanochemical synthesis route.
