Synthesis, Structure, and Optical Properties of a Ca(II) Complex With Biphenyl-2,3,3′,5′-tetracarboxylic Acid

A new 1-D calcium complex [Ca(H 2 bptc)(H 2 O) 3 ] n (1) (H 4 bptc = biphenyl-2,3,3′,5′-tetracarboxylic acid) were obtained by hydrothermal reaction. X-ray diffraction analysis shows that complex 1 crystallizes in the monoclinic space group P2(1)/c with a = 14.3376(13), b = 11.3116(10), c = 11.9099(...

Summary:A new 1-D calcium complex [Ca(H 2 bptc)(H 2 O) 3 ] n (1) (H 4 bptc = biphenyl-2,3,3′,5′-tetracarboxylic acid) were obtained by hydrothermal reaction. X-ray diffraction analysis shows that complex 1 crystallizes in the monoclinic space group P2(1)/c with a = 14.3376(13), b = 11.3116(10), c = 11.9099(11), β = 114.0740(10), V = 1763.6(3)Å 3 , Z = 4, D c = 1.591 g·cm −3 , μ = 0.417 mm −1 , F(000) = 872, and the final R 1 = 0.0310, wR 2 = 0.0812 for I>2σ(I). Central Ca(II) ion is seven-coordinated and exhibits a distorted pentagonal bipyramidal geometry. Additionally, the IR, TG, UV-Vis absorption, and luminescence properties of 1 have been investigated.
