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.

在室温和高压下，已经研究了BIS（1,2-二离子二氧化碳）铂（II）铂（II）铂（II）铂（II）铂（II）铂（II）的绝缘体到金属对导体的转变。为了了解这些过渡的机制，我们必须在低温和高压下研究这些复合物的电性能。已准备好新的高压设备来测量在低温（T）和高磁场（H）下这些复合物的物理参数。该设备可分别用于压力（P），T和H，0 <P <3 GPA，1.3 <T <300 K和0 <H <7 Tesla。可以在许多冷凝物中进行电导率，磁化率，热膨胀系数和磁静脉的测量。这些配合物中的结构异常是在高压下发现的。这些与高压下有趣的电气行为密切相关。
