Abstract

A new complex, [In(2)(mu-OH)(2)(btc)(2)](n)().2nHpy (1) (btc = 1,3,5-benzenetricarboxylate; py = pyridine), is hydrothermally synthesized from the reaction of InCl(3), H(3)btc, and pyridine. Complex 1 crystallizes in the monoclinic P2(1) space group [a = 7.3181(12) A, b = 17.0195(23) A, c = 10.5789(17) A, beta = 102.651(6) degrees , and Z = 2]. Indium(III) centers in 1 are bridged by btc ligands in various coordination modes to form the nonclose rings which are further interlinked along crystallographic a-axis and (011) plane to result in a nonpenetrated 3-D anionic framework growing as homochiral tunnels. Compound 1 is fully characterized by fluorescence spectroscopy, second harmonic generation measurement, infrared, and thermogravimetric analysis.
