A detailed study of the two-step spin-state conversion in 4,7,10))] is presented with special emphasis on the structural changes evidenced by a multitemperature X-ray crystal and molecular structure study (292, 153, 103 K). The ligand (5-NO2-sal-N(l,4,7,10)) results from the Schiff base condensation of 5-nitrosalicylaldehyde with tetraazadecane in a 2:1 ratio. The
X-ray and neutron diffraction measurements at 1 I O K have been used to determine the deformation electron density for hydrogen peroxide (H202). The oxygen atom has been observed to be in a sp3 hybridization state with one of the lone pairs involved in hydrogen bonding. No charge accumulation has been found in the oxygen-oxygen bond. This is explained as a result of the difference technique used. but does indicate that the transfer of electrons to the binding region is relatively small during bond formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
