Tl I three-dimensional coordination polymer involving tetranuclear cubic cage nodes, [Tl 4(μ 8-SB) 2] n{H 2SB = 4-[(4-hydroxyphenyl)sulfonyl]-1-benzenol}

Abstract

The single crystal X-ray analysis of a novel Tl I coordination polymer of 4-[(4-hydroxyphenyl)sulfonyl]-1-benzenol (H 2SB) ligand shows that the complex is a three-dimensional polymer as a result of bridging “SB 2−” ligands with basic repeating [Tl 4(μ 8-SB) 2] units. There are four thallium atoms with different coordination spheres in the cubic cage. These thallium atoms contain irregular coordination sphere with stereo-chemically active lone pair and thallium–thallium interactions, Tl(1)O 4, Tl(2)O 4Tl 2, Tl(3)O 4Tl and Tl(4)O 3Tl.
