NITRATO ADDUCTS AND DERIVATIVES: SYNTHESIS AND INFRARED STUDY
Journal Title: Journal of Engineering Studies and Research - Year 2017, Vol 23, Issue 1
Abstract
Five new nitrato adducts and derivatives have been synthesized and studied by infrared spectroscopy. The suggested structures are discrete or of infinite chain type, the nitrate behaving as a bidentate or a monodentate ligand, the environment around the tin (IV) centres being octahedral or trigonal bipyramidal. When extra hydrogen bonds are considered supramolecular architectures may be obtained.

NEW PYRIDINE-3-SULFONATO TIN (IV), ANTIMONY (III) AND (V) HALO ADDUCTS AND COMPLEXES: SYNTHESIS AND INFRARED STUDY
Six new tin (IV), antimony (III) and antimony (V) adducts and complexes have been synthesized. Discrete structures were suggested on the basis of infrared data. Within the structures, the anion behaves as a bidentate, mo...
