Abstract

A new dioxomolybdenum(VI) compound [MoO2(L) · C5H5N], where L2– is 2-[N-(2-hydroxynaphthalidene)amino]propane-1,2,3-triol, was synthesized and its structure was determined by IR spectroscopy and X-ray diffraction. The Mo atom is in an octahedral coordination environment formed by two oxo ligands in cis positions to each other, two O atoms and the N(2) atom of the tridentate bis(chelate) ligand L, and the N(1) atom of the pyridine (Py) molecule. The N(2)(L) and N(1)(Py) atoms are in trans positions to the O(oxo) ligands at distances that are elongated due to the structural trans effect of the multiply bonded oxo ligands (Mo–N(1), 2.476 Å; Mo–N(2), 2.272 Å).

溶剂化配合物[MoO 2(L)·C 5 H 5 N]的合成,晶体和分子结构,其中L 2–是2- [N-(2-羟基萘)氨基]丙烷-1,2,3-三醇阴离子

摘要

合成了一种新的二氧钼(VI)化合物[MoO 2L)·C 5 H 5 N],其中L 2–为2- [ N-(2-羟基萘)氨基]丙烷-1,2,3-三醇。通过红外光谱和X射线衍射确定其结构。Mo原子处于八面体配位环境,由两个彼此顺式排列的氧代配体,两个O原子和三齿双(螯合物)配体L的N(2)原子以及该原子的N(1)原子形成。吡啶(Py)分子。N(2)(L)和N(1)(Py)原子处于反式O(oxo)配体的位置由于多重键合的oxo配体的结构反式作用而变长了(Mo–N(1),2.476Å; Mo–N(2),2.272Å)。
