Preparation, characterization, and X-ray crystal structure of a one-dimensional calcium-based coordination polymer with strong blue fluorescent emission

Abstract

The hydrothermal reaction of 4-cyanobenzoic acid with Ca(ClO 4) 2·6H 2O yields the one-dimensional calcium-based coordination polymer [Ca(L) 2(H 2O) 2] n 1 (where L= 4-cyanobenzoic acid) with strong blue fluorescent emission, and its solid-state structure has been characterized by X-ray single-crystal diffraction studies. Crystal data for 1: monoclinic, space group P2/ n, a=7.154 (2), b=16.402 (3), c=7.549 (2) Å; β=115.83 (2)° ; Z=2; R=0.0536 for 1410 independent reflections with I>2 α( I).
