| 英文摘要 | A new electrical conductive crystal PyEt[Ni(dmit)2]2 (dmit = 4,5-dimercapto-1,3-dithiole-2-thione) has been synthesized and its X-ray structure has been determined to be in monoclinic system, C2/c space group. In PyEt[Ni(dmit)(2)](2) crystal, the conducting component [Ni(dmit)(2)](0.5-) is face-to-face packed forming molecular column along the c-direction, and these molecular columns are then side-by-side extended along the a-direction forming a kind of two-dimensional conducting sheet on (010). The measured conductivity at room temperature along a certain direction on,(010) plane is 10 S (.) cm(-1). From 282 to 269 K, the crystal shows metallic behavior but changes to semi-conductor below 269 K Based on the measured crystal structure, and calculated band structure, this conductor-semiconductor phase transformation can be primarily interpreted: The metallic conductivity is corresponding to the uniform molecular column and the atomic-lattice-chain structure of Ni chain, while the semi-conductive behavior to staggered molecular column and the atomic-zigzag-chain structure of Ni chain. |
