spectrum of Al(CO)2, observed in deposits of Al atoms and CO in adamantane at 77 K, has a symmetric CO stretching mode at 1985 cm–1 and antisymmetric CO stretching mode at 1903.8 cm–1; there is i.r. evidence for the formation of Al2CO and Al2(CO)4 in this system.
在77 K的
金刚烷中在Al原子和CO的沉积物中观察到的Al(CO)2的ir光谱在1985 cm –1处具有对称的CO拉伸模式,在1903.8 cm –1处具有反对称的CO拉伸模式;有没有证据表明在该系统中会形成Al 2 CO和Al 2(CO)4。
