Abstract

We report the synthesis of molybdenum and tungsten bromo dicarbonyl complexes (POCOP^t^Bu)M^IIBr(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 Mo^II and W^II complexes adopt a six-coordinate distorted trigonal prismatic geometry, whereas the Cr⁰ complex exhibits a distorted octahedral geometry.

螯合6族(Cr, Mo, W)羰基配合物的合成、表征及液相注入场解吸电离质谱分析。

本文报道了钼钨溴二羰基配合物(POCOPtBu)MIIBr(CO)2 (M = Mo或W;POCOPtBu = κ3- c6h3 -1,3-[OP(tBu)2]2)由阴离子PCP钳形配体支撑，而铬配合物(PNPtBu)Cr0(CO)3 (PNPtBu = 2,6-二(二叔丁基膦甲基)吡啶)承载中性PNP钳形支架。本研究中描述的三个六族配合物已通过液体注射场解吸电离质谱(LIFDI-MS)，核磁共振和红外光谱进行了表征。单晶x射线衍射研究表明，MoII和WII配合物具有六坐标畸变三角棱柱几何结构，而Cr0配合物具有畸变八面体几何结构。
