Abstract
Abstract The compounds [Fe(phen)3]Hg2Sn2Se7·1.5eta·0.25H2O (phen = 1,10-phenanthroline; eta = ethanolamine) (1) and [Ni2(teta)2(μ-teta)]HgSn3Se9 (teta = triethylenetetramine) (2), have been synthesized under solvothermal conditions, which represent the first examples of mercury chalcogenidostannates incorporating transition metal (TM) complexes as counter cations and structure-directing agents. Compound 1 features a one-dimensional (1D) ribbon of [Hg2Sn2Se7]n2n− based on the {Hg2Sn2Se9} secondary building unit, whereas 2 features a 1D zigzag chain of [HgSn3Se9]n4n− assembled by the linkage of {HgSn3Se10} supertetrahedral T2 clusters. The optical absorption edges of 1 and 2 are estimated to be 1.88 and 2.29 eV, respectively. Thermal stabilities of 1 and 2 were investigated via thermogravimetric analyses.
