研究了过渡金属羰基化合物[L(CO)NM](Na/K)(M=Cr，Mo，W，Mn，Re，Fe，Co，Ni；L=CO，N5-C5R5，Pr3；n=1-4；R=烷基，芳基)与碱稳定的卤化镓化合物ClaGaR3-a(DO)(R=H，烷基，卤化物；DO=THF，N(CH3)3，NC7H13)或ClGa[(CH2)3N-R2](R)2-a分别几乎定量地合成了过渡金属取代的[L(CO)NM]aGaR3-a(DO)和[L(CO)n-M]AgA[(CH2)3NR2](R)2-a。这些络合物中残留的卤化物官能团被各种其他基团选择性地取代。新化合物经元素分析、1H-、13C-、31P-核磁共振、MS和LRv(CO)数据确证。单晶X射线单晶结构分析表明，反式(Ph_3P)(CO)_3Co-Ga[(CH_2)_3N(C_2H_5)_2](R)(6S：R=Cl，6T：R=CH_3)的Co-Ga的长度分别为237.78(4)和249.5(1)pm。发现(N5-C5H5)(CO)2Fe-Ga-Cl2[N(CH3)3](5a)的S(Fe-Ga)短接触为236.18(3)pm。进行了低压MOCVD实验，获得了分析纯的CoGa合金薄膜。
The salt elimination reaction of the transition carbonyl metal-lates [L(CO)nM](Na/K) (M = Cr, Mo, W, Mn, Re, Fe, Co, Ni; L= CO, n5-C5R5, PR3; n= 1-4; R= alkyl, aryl) with the base-stabilized galliumhalides ClaGaR3 -a(Do) (R = H, alkyl, halide; Do = THF, N(CH3)3, NC7H13) or ClaGa[(CH2)3N-R2](R)2 - a yielded almost quantitatively the transition metal-substituted, gallanes [L(CO)nM]aGaR3 - a(Do) and [L(CO)n-M]aGa[(CH2)3NR2](R)2 - a, respectively. Residual halide functionalities in these complexes were selectively replaced by various other groups. The new compounds were characterized by means of elemental analysis, 1H-, 13C-, 31P-NMR, MS, and lR v(CO) data. The single-crystal X-ray structure analysis of trans-(Ph3P)(CO)3Co-Ga[(CH2) 3N(C2H5)2](R)( 6s: R = Cl, 6t: R= CH3) showed s(Co-Ga) lengths of 237.78(4) and 249.5(1) pm, respectively. A short s(Fe-Ga) contact of 236.18(3) pm was found for (n5-C5H5)(CO)2Fe-Ga-Cl2[N(CH 3)3] (5a). Low-pressure MOCVD experiments were performed to give thin films of analytically pure CoGa alloy.
