Synthesis and characterization of an organic-inorganic hybrid crystal: 2[Co(en)](VO)·4HO. | LitMetric

AI Article Synopsis

Article Abstract

Organic-inorganic hybrid crystals have diverse functionalities, for example in energy storage and luminescence, due to their versatile structures. The synthesis and structural characterization of a new cobalt-vanadium-containing compound, 2[Co(en)](VO)·4HO (1) is presented. The crystal structure of 1, consisting of [Co(en)] complexes and chains of corner-sharing (VO) tetrahedra, was solved by single-crystal X-ray diffraction in the centrosymmetric space group P1. Phase purity of the bulk material was confirmed by infrared spectroscopy, scanning electron microscopy, elemental analysis and powder X-ray diffraction. The volume expansion of 1 was found to be close to 1% in the reported temperature range from 100 to 300 K, with a volume thermal expansion coefficient of 56 (2) × 10 K. The electronic band gap of 1 is 2.30 (1) eV, and magnetic susceptibility measurements showed that the compound exhibits a weak paramagnetic response down to 1.8 K, probably due to minor Co impurities (<1%) on the Co site.
