3-Formylcamphor Co(III) complexes of a tripod-like ligand, tren, were prepared and the two possible geometrical isomers were separated successfully. The crystal structure of one of them was determined by X-ray diffraction. A red plate-like crystal was monoclinic, space group P21, a=12.401 (2), b=9.9400 (7), c=10.932 (1) Å, β=108.44 (1)°, and Z=2. The structure was refined to R=0.047 on 2818 reflections. The geometrical isomers were compared sepectroscopically.
制备了三脚架配体 tren 的 3-甲酰基樟脑 Co(III)配合物,并成功分离了两种可能的几何异构体。通过 X 射线衍射确定了其中一种的晶体结构。红色板状晶体为单斜晶体,空间群为 P21,a=12.401 (2),b=9.9400 (7),c=10.932 (1)埃,β=108.44 (1)°,Z=2。在 2818 次反射中,结构精制为 R=0.047。对几何异构体进行了分离光谱比较。
