本研究利用固態高溫長晶法，或是加入助熔劑(flux)成功合成出兩種不同結構的新穎四元硫鹵族化合物。
化合物1為三維結構，晶系為orthorhombic Pnma。其結構的組成是由一個五配位的Bi(1)以及四個四配位的Cu，分別是Cu(1)、Cu(2)、Cu(3)以及Cu(4)，相互串接，形成一個分子。再藉由對稱操作，堆疊成完整三維結構。性質部分，能係(band gap)為0.35e.V，而且在室溫下，電導率σ (Electrical Conductivity)值為300S/cm，電熱勢S (Thermopower)為-75μV/K，熱傳導係數κ (Thermal Conductivity)為0.5W/mK，其熱電優值ZT(Thermoelectric figure of merit)為0.1，並且顯現出為n-type熱電材料。
化合物2亦為一新穎三維結構。晶系為Monoclinic P2/m。其結構的組成，是由Cu(1)四面體和三個五配位的Sb(1)、Sb(2)、Sb(3)以及六配位Sb(4)互相串接而形成一個分子，倆倆分子藉由Cu(1)橋接而構成一個單位晶胞(Z=2)，並且倆倆單位晶胞藉由Sb(4)橋接沿ac平面延伸，再延b軸相上堆疊而成，形成三維結構。其結構特殊，像是電線結構，外層為藍色區塊CuSe2I2，包覆著內層紅色區塊SbSe5和SbSe6。

We have successfully synthesized two metal chalcohalide compounds by a high temperature solid state and flux-growth method.

Compound 1 adopts a three-dimensional structure, which crystallizes in orthorhombic Pnma. The framework is composed of five-coordinated Bi(1) and three four-coordinated Cu atoms, respectively. The Cu(1), Cu(2), Cu(3)and Cu(4) are connected to form a molecule. The UV-Vis reflection spectrum reveals 0.35e.V . At room temperature, the values of electrical conductivity σ is 300S/cm, thermopower S is-75μV / K , thermal conductivity κ is 0.5W/mK.

Compound 2 adopts a new three-dimensional structure. which crystallizes in Monoclinic P2/m. The framework is composed of tetrahedral Cu(1) and three five-coordinate Sb(1), Sb(2), Sb(3) and a six-coordinated Sb(4) are connected to form a molecule.
