Insulator-to-metal-to-semiconductor transitions of bis (1,2-dionedioximato) platinum (II) complexes have been studied at room temperature and high pressure. In order to understand the mechanism of these transitions we must investigate the electrical properties of these complexes at low temperatures and high pressures. New high pressure apparatus has been prepared to measure the physical parameters of these complexes at low temperatures (T) and at high magnetic fields (H). The apparatus can be used in the range of pressure (P), T and H,0<P<3 GPa, 1.3<T<300 K,and 0<H<7 tesla, respectively. The measurements of the electrical conductivity, magnetoresistance, thermal expansion coefficients and magnetostriction can be carried out for many condensed matters.The X-ray diffraction of bis (1,2-dione dioximato) platinum (II) complexes with synchrotron radiation has been studied ; the structural anomalies in these complexes were found at high pressures. These are closely related to interesting electrical behavior at high pressures.

本文研究了双（1，2-二酮二肟基）铂（II）配合物在室温和高压下的绝缘体-金属-半导体转变。为了理解这些转变的机制，我们必须研究这些配合物在低温和高压下的电学性质。研制了新的高压装置，用于测量这些配合物在低温（T）和高磁场（H）下的物理参数。该装置可以在压力（P）、T和H的范围内使用，分别为0<P<3GPa、1.3<T<300 K和0<H<7特斯拉。用同步辐射X射线衍射研究了双（1，2-dione dioximato）铂（II）配合物的结构，发现了高压下的结构异常。这些与高压下有趣的电气行为密切相关。
