Germanium chalcogenides have attracted wide attention in inorganic chemistry because of their flexible structure and rich properties. Five new germanium containing transition metals such as manganese, zinc, cadmium were synthesized by solvothermal methods using alkali structural directing agents. Rb2MnGeSe4 (1), Cs2MnGeSe4 (2), Cs2ZnGeSe4 (3) a one-dimensional chain Rb2Zn2GeSe4·H2O (4) Rb2CdGeSe4 (5) two-dimensional layer structure. The electronic structure, band gap, photocurrent response compounds 1-5 been comprehensively analyzed. Due to the layered 4 5, we studied ion-exchange Compounds 5 showed excellent properties could be used potential materials for absorption radioactive elements nuclear wastewater.

The hare and the hedgehog – Similar thermal expansion of argento- and aurophilic contacts for different reasons

Abstract This study investigates the thermal expansion properties of argentophilic and aurophilic contacts in coordination complexes form [( i Pr NHC) 2 Ag]ClO 4 Au]ClO . Using X-ray crystallography distinct structural changes phase transitions at varying temperatures are revealed. Both exhibit a similar strong temperature dependence metallophilic distances. Analysis shows that shallower, more anharmonic interaction is counterbalanced by smaller vibrational amplitude heavier gold atoms, resulting comparable elongation despite differing atomic dynamics.
