利用Co4(CO)10HCCCOOH与Eu(OOCCF3)3反应合成了一种新型的含羧酸配体的钴羰基簇合物Co3(CO)9(μ3-CCH2COOH),并对簇合物进行了C/H元素分析、IR和TGA等表征,同时测定了簇合物的晶体结构.簇合物Co3(CO)9(μ3-CCH2COOH)结晶于三斜晶系,属于P-ī点群.晶胞参数a()=8.2074(7),b()=13.5852(12),c()=15.9065(14),α(°)=95.6430(10),β(°)=101.035(2),γ(°)=86.056(2),Z=1,F(000)=1887,分子结构呈中心对称.
A new type of cobalt carbonyl cluster Co3 (CO) 9 (μ3-CCH2COOH) with carboxylic acid ligand was synthesized by the reaction of Co4 (CO) 10HCCCOOH with Eu (OOCCF3) 3. H elemental analysis, IR and TGA were used to characterize the crystal structure of the cluster. The crystal structure of the cluster compound Co3 (CO) 9 (μ3-CCH2COOH) crystallized in the triclinic system, a () = 8.2074 (7), b () = 13.5852 (12), c () = 15.9065 (14), α (°) = 95.6430 (10), β (°) = 101.035 γ (°) = 86.056 (2), Z = 1, F (000) = 1887, the molecular structure was centrosymmetric.
