我们报道了由阴离子PCP钳形配体支撑的钼和钨溴代二羰基配合物（POCOP t Bu）MIIBr（CO）2（M = Mo或W; POCOP t Bu = κ3-C6 H3 - 1，3-[OP（tBu）2]2）和带有中性PNP钳形骨架的铬配合物（PNP t Bu）Cr 0（CO）3（PNP t Bu = 2，6-双（二叔丁基膦甲基）吡啶）的合成。在这项研究中所描述的三组六配合物已通过液体注射场解吸电离质谱（LIFDI-MS），NMR和IR光谱进行了表征。单晶X-射线衍射研究表明MoII和WII配合物采用六配位扭曲的三角棱柱几何结构，而Cr 0配合物表现出扭曲的八面体几何结构。
We report the synthesis of molybdenum and tungsten bromo dicarbonyl complexes (POCOP t Bu)MIIBr(CO)2 (M = Mo or W; POCOP t Bu = κ3-C6H3-1,3-[OP(tBu)2]2) supported by an anionic PCP pincer ligand, and the chromium complex (PNP t Bu)Cr0(CO)3 (PNP t Bu = 2,6-bis(di-tert-butyl-phosphinomethyl)pyridine) bearing a neutral PNP pincer scaffold. The three group six complexes described in this study have been characterized by Liquid Injection Field Desorption Ionization Mass Spectrometry (LIFDI-MS), NMR, and IR spectroscopy. Single crystal X-ray diffraction studies show the MoII and WII complexes adopt a six-coordinate distorted trigonal prismatic geometry, whereas the Cr0 complex exhibits a distorted octahedral geometry.
