Synthesis and crystal structure of one new cadmium coordination polymer constructed by phenanthroline derivate and 1,4-naphthalenedicarboxylic acid

Abstract A cadmium coordination polymer, [Cd(1,4-NDC)(L)] n ( 1 ), has been hydrothermally synthesized by using 1-(1 H -imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol (L) and 1,4-naphthalenedicarboxylic acid (1,4-H 2 NDC). The complex 1 was characterized by diffraction and elemental analyses. In complex 1 , the cadmium ion is distorted octahedral coordinated linking the deprotonated 1,4-NDC anion to form a two-dimensional (2D) layer, and the 2D layer are associated into 3D supramolecular structure via the strong π–π stacking interactions from the conjugated L ligands. In addition, thermogravimetry, powder X-ray diffraction, and the solid-state photoluminescent properties of complex 1 were also studied.
