[Ni(dien)2]3[Ge3Sb8S_(21)]·0.5H2O: A new 2-D layered thiogermanate-thioantimonate with metal complexes as template ions

摘要

A new 2-D layered thiogermanate-thioantimonate [Ni(dien)2]3[Ge3SbsS_(21) ] · 0.5H2O (1, dien = diethylenetriamine) was synthesized under solvothermal conditions and structurally characterized. The polymeric [Ge3Sb8S_(21)]~(6n-)_n anion in 1 is composed of heterometallic semicube [GeSb2S7] clusters and trigonal-pyramidal [SbS3] units, which are interconnected to build a 2-D layer with the large Sb_(18)S_(18) heterorings. The apertures of the Sb_(18)S_(18) heterorings are filled by three [Ni(dien)2]~(2+) complex cations as template ions. The absorption band edge of 1 is 2.29 eV, exhibiting properties of the semiconductor.
