结论（CH 3）3Ga和AsH 3的混合物在14 K下共沉积到惰性基质中，形成了1：1的分子加合物。该物种的特征在于由一些扰动振动模式，并通过同位素标记确认频带分配。的加合物的结构似乎是与一个明显的扭曲的GaC 3骨架从平面性。这种结构，沿着与所观察到的振动位移，是在良好的协议与从头计算类似的H3 Ga <AsH 3加合物。还获得了这种复合物在室温下存在的证据，无论是在气相中，还是在气相中，都可能凝结在气室的窗口上。作者感谢国家科学基金会通过CHE 90-24474资助这项研究。
ConclusionsThe codeposition of mixtures of (CH3) 3Ga and AsH3 into inert matrices at 14 K has given rise to the formation of a 1: 1 molecular adduct. This species was characterized by a number of perturbed vibrational modes, and band assignments were confirmed by isotopic labeling. The structure of the adduct appears to be with a distinct distortion of the GaC3 skeleton from planarity. This structure, along with the observed vibrational shifts, are in good agreement with ab initio calculations on the analogous H3Ga< AsH3 adduct. Evidence was also obtained for the existence of this complex at room temperature, either in the gas phase or possibly in the liquid phase condensed on the windows of the gas cell.Acknowledgment.
