Synthesis and structure of a copper sulfate/kinked organodiimine coordination polymer entraining “infinite” decorated water chains with C14 classification

The 1D chain coordination polymer {[Cu(SO4)(dpmd)2] · 8H2O} (1, dpmd = 4,4′-dipyridylmethanediol) has been prepared by a solution phase method and characterized by single-crystal X-ray diffraction, IR and thermogravimetric analysis. The dpmd ligand was formed in situ from 4,4′-dipyridylketone. Decorated 1D water molecule chains with a very rare C14 classification co-crystallized and were stabilized within the coordination polymer matrix.
