摘要：
A new metal chalcogenide,γ-HgSBr(1),has been prepared by moderate-temperature solidstate reaction,and its crystal structure was determined by single-crystal X-ray diffraction analysis.Compound 1 crystallizes in space group Cmmm of orthorhombic system with a=9.1923(18),b=18.2262(5),c=4.625 1(7) A,V=774.9(3) A~3 and Z=4.In the structure,two Hg(1),two Hg(2) and four S(1) atoms form a near square HgS,and such squares are linked by Hg(3) atoms nearly linearly coordinated to two S1 atoms of two parallel HgSsquares to form one-dimensional infinite HgSchains along c direction.Optical absorption spectra reveal the presence of sharp optical gap of 2.80 eV for 1.1 R spectrum,TGA and electric resistivity have been investigated.
