其中Dieten=N，-N-二乙二胺，X=无机阴离子，M(Dieten)/sub2/X/sub2/型铜(II)和镍(II)配合物的热致变色机理尚未明确。对电子区和红外区(中红外和远红外)进行了压力和热研究。在电子区，随着温度的升高，Cu(II)和Ni(II)络合物的d-d跃迁红移。在加压下，铜(II)络合物向红色跃迁，Ni(II)络合物向蓝色跃迁。中红外数据表明，随着温度的升高，轴向相互作用发生，而随着压力的增加，缺乏相互作用。尽管决定这些差异的因素很多，阴离子和空间效应也很重要，但主导因素似乎是四方金属原子环境的扭曲以及阴离子与M-N/sub4/平面之间的轴向相互作用。
The thermochromic mechanism of several Cu(II) and Ni(II) complexes of the type M(dieten)/sub 2/X/sub 2/, where dieten = N,-N-diethylethylenediamine and X = inorganic anion, has not been clearly established. Pressure and thermal studies in the electronic and infrared region (mid-infrared and far-infrared) have been made. In the electronic region, the ''d-d'' transitions shift red with an increase in temperature for both Cu(II) and Ni(II) complexes. With pressure these transitions are toward the red with Cu(II) complexes and toward the blue with Ni(II) complexes. Mid-infrared data are indicative of axial interaction occurring with an increase in temperature and the lack of interaction with pressure increases. Although many factors are involved in determining these differences and anion and steric effects are important, the dominant factor appears to be the distortion of the tetragonal metal atom environment and axial interaction between the anions and the M-N/sub 4/ plane.
