Synthesis and Structures of Copper and Thallium(I) Coordination Compounds [Cu2[B10H10]]n and Tl2[B10H10] with the closo-Decaborate Anion

Abstract

Solvent-free copper(I) and thallium(I) compounds of the general formula [M2[B10H10]] have been synthesized. The compounds have been identified by IR spectroscopy and X-ray diffraction. According to X-ray diffraction data, the structures of both compounds are three-dimensional frameworks. In copper(I) complex [Cu2[B10H10]]n, the formation of three-center M–H–B bonds is observed. In thallium(I) compound Tl2[B10H10], the bond between cations and anions is ionic, which is confirmed by IR spectroscopy data. The Hirschfeld surface analysis of the boron cluster anion was performed for both compounds to identify and analyze intramolecular interactions.

Glycols in the Synthesis of Zinc-Anilato Coordination Polymers

We report the synthesis, structural investigation, and thermal behavior for three zinc-based 1D-coordination polymers with 3,6-di-tert-butyl-2,5-dihydroxy-p-benzoquinone, which were synthesized in the presence of different glycols. The interaction of zinc nitrate with glycols, followed by using the resulting solution in solvothermal synthesis with the anilate ligand in DMF, makes it possible to obtain linear polymer structures with 1,2-ethylene or 1,2-propylene glycols coordinated to the metal. The reaction involving 1,3-propylene glycol under similar conditions gives a crystal structure that does not contain a diol. The crystal and molecular structures of the synthesized compounds were determined using single crystal by X-ray structural analysis. The influence of glycol molecules coordinated to the metal on the thermal destruction of synthesized compounds is shown.
