柠檬酸盐铵及其相应的羧酸盐与钼(0)羰基配合物(C7H8)Mo(CO)3反应生成(Et4N)3[(HCIT)Mo(CO)3](1)、(Et4N)2[(Hcmal)Mo(CO)3](2)、(Et4N)2[(Hmmal)Mo(CO)3](3)和(Me4N)2[(Meida)Mo(CO)3](4)。用红外光谱、紫外可见光谱、−-Vis光谱和元素分析对配合物1-−-4进行了表征。用X-射线衍射法测定了所有配合物的分子结构。钼中心采用八面体配位几何构型，三个羰基和一个三齿配体与钼的羧基、羟基或氮原子显示出独特的配位作用。
Reactions of ammonium salts of citrate and its relevant carboxylates with a molybdenum(0) carbonyl complex (C7H8)Mo(CO)3 resulted in the formation of (Et4N)3[(Hcit)Mo(CO)3] (1), (Et4N)2[(Hcmal)Mo(CO)3] (2), (Et4N)2[(Hmal)Mo(CO)3] (3), and (Me4N)2[(Meida)Mo(CO)3] (4), which are the first examples of organo-molybdenum complexes having a tri- or dicarboxylate. Complexes 1−4 were characterized by means of IR and UV−vis spectra and elemental analyses. Molecular structures of all complexes were determined by an X-ray diffraction study. The molybdenum center adopts an octahedral coordination geometry with three carbonyl ligands and a tridentate ligand which displays a unique coordination to molybdenum with its carboxylates and hydroxyl group or nitrogen atom.
