Self-assembly and crystal structure of a barium sulfonate chrysin coordination polymer

摘要

A novel barium coordination polymer [Ba(C_(15)H_9O_7S)_2]_n was obtained by the self-assembly of Ba(II) with a sulfonate derivative of chrysin(5,7-bihydroxyflavone-6-sulfonate).The coordination polymer was characterized by single-crystal X-ray diffraction.Its bar-ium(II) atom is in distorted dodecahedron environment of 10 oxygen atoms.The coordination interaction,hydrogen bond and pi-pi stacking lead to the formation of a 1D chain structural coordination polymer.
