Abstract

ABSTRACT: A new Ho(II) polymer [Ho(ctdc)]n 1 (H3 ctdc = 5′-(4-Carboxyphenyl)-[1, 1′:3′, 1′′-terphenyl]-4, 4′′-dicarboxylic acid) was synthesized under hydrothermal conditions. The compound crystallizes in the Monoclinic system, space group P2(1)/c with a = 17.5782(4), b = 28.6807(5), c = 9.5889(2)Å, α = 90, β = 101.956(2), γ = 90°, V = 4729.44(16) Å 3, Z = 4, Mr = 618.34, Dc = 0.868 Mg/m 3, μ = 3.321 mm −1, F (000) = 1208, the final R = 0.0723 and wR = 0.2343 for 5974 observed reflections with I > 2σ( I ). The compound presents a three-dimensional (3 D) network extended by both ctdc 3− anions in which the ctdc 3− anions employ a chelating coordination mode. From the topology point of view, the structure could be described as a 6-connected 3 D network with (4 6 . 6 4 ) topology net. Infrared spectroscopy, elemental analyses, thermogravimetric analysis and powder X-ray diffraction properties of1 are also investigated.
