摘　　要：本文报道了二氧杂钼配合物[MoO_(2)(H_(2)L)(H_(2)O)]的合成、表征和分子结构。该配合物是由马来酰二腙配体双(2-羟基-1-萘醛)丙二酰二腙(H4L)与双(乙酰丙酮)二氧钼在甲醇中以1∶1的物质的量之比反应得到的。通过各种光谱(如IR、MS和NMR)对该配合物进行了表征。通过单晶X射线晶体学确定了配合物的结构。该配合物属于单斜晶系P2_(1/c)空间群。金属中心具有扭曲的八面体配位环境,与H_(2)L^(2-)的1个甲亚胺氮原子、2个末端氧基团、H_(2)L^(2-)的2个氧原子和配位水分子的1个氧原子相连。In this paper,we report the synthesis,characterization,and molecular structure of the dioxidomolybdenum􀃱complex[MoO_(2)(H_(2)L)(H_(2)O)].The complex was obtained by reaction of malanoyldihydrazones ligand bis(2‑hydroxy‑1‑naphthaldehyde)malonoyldihydrazone(H4L)with molybdenum bis(acetylacetonato)dioxomolybdenum􀃱in a 1∶1 molar ratio in methanol.The complex was characterized by using various spectroscopic studies,such as IR,MS,and NMR.The structure of the complex was established by single‑crystal X‑ray crystallography.The complex crystallizes in the monoclinic space group P2_(1/c).The metal center has distorted octahedral coordination environments,connected to one azomethine nitrogen atom of H4L,two terminal oxido groups,two oxygen atoms of H4L,and one oxygen atom of a coordinated water molecule.
