X-ray absorption near edge structure spectroscopy has been used to establish the chemical shifts of the technetium K edge in a range of compounds containing Tc in a variety of formal oxidation states. The edge positions span 19.9 eV from Tc metal to

The effect of the anion in a crown ether-cation structure is examined by comparing the structure of [{Na(C 20 H 36 O 6 )}(ReO 4 )] with one containing the same crown ether and cation, but a different anion. The title compound shows that the crown eth

XANES (X-ray Absorption Near Edge Spectroscopy) has been employed to evaluate the efficacy of a process designed to encapsulate and reduce TcO4-in cement matrices, thereby immobilizing Tc. The oxidation state of Se following bioremediation of Se by b

The title complex, [ReCl 3 O(C 18 H 15 OP)(C 18 H 15 P)], is produced in a reaction between [Re(O)Cl 3 (PPh 3 ) 2 ] and ethyl 2-hydroxymethyl sulfoxide. The structure is compared to that of [Re(O)Cl 3 (PPhEt 2 )(OPPhEt 2 )] The Re-Cl distances are sh
