Abstract

Two cadmium(II) complexes based on 2-(3-(pyridin-2-yl)-1H-pyrazol-1-yl)benzoate with chemical formulas of [Cd2(ppb)4(H2O)2]·8H2O (1) and [Cd(Hppb)I2]n (2) (Hppb = 2-(3-(pyridin-2-yl)-1H-pyrazol-1-yl)benzoic acid), have been synthesized. Both complexes are well characterized by IR, TGA and X-ray single-crystal as well as powder diffraction. Structural analyses reveal that 1 is a binuclear complex and 2 has one-dimensional polymers, respectively, in which they are expanded to three-dimensional supramolecular structures by hydrogen bonds. The Cd(II) coordinated environments in 1 are slightly distorted octahedral geometries, but central atoms in 2 display distorted square pyramidal geometries. There are obvious differences in ligation modes of the ppb or Hppb ligands for both complexes. In 1, four ppb ligands are divided into two groups, displaying µ1-kN, N′ and µ2-kN, N′: kO coordination modes. Two ppb ligands act as two µ1,6-bridges linking the binuclear Cd(II) cations with a distance of 6.282(2) Å. In 2 the neutral Hppb ligands exhibit a µ2-kN, N′: kO coordination mode, and connecting Cd(II) ions by µ1,6-bridges and forming an infinite 1D chain along b axis. Hirshfeld surfaces and fingerprint plots analyses indicate that weak interactions of C–H···π, π···π, O–H···O or O–H···I play important roles in crystal packings of 1 and 2. Luminescent measurements in solid-state show their different intensities in the luminescences of 1 and 2.

Graphical Abstract

A binuclear complex [Cd2(ppb)4(H2O)2]·8H2O (1) and a one-dimensional complex [Cd(Hppb)I2]n (2) were synthesized and characterized by X-ray crystal diffraction. Investigation of solid-state luminescence properties indicates the blue shifts of the emission λmax of complexes.
