Abstract
The two independent N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(NO(3))(6)], exist in the zwitterionic form. One of these binds to one metal center, whereas the other bridges two metal centers. The La atom is chelated by three nitrate groups and is surrounded by nine O atoms in a coordination environment based on a distorted monocapped square-anti-prism. The dinuclear structure is further stabilized by intra-molecular N-H⋯O(nitrate) hydrogen bonds.
摘要
在中心对称的标题化合物[La₂(C₁₀H₉NO)₄(NO₃)₆]中，两个独立的N - 杂环以两性离子形式存在。其中一个与一个金属中心结合，而另一个桥连两个金属中心。La原子被三个硝酸根螯合，并在基于扭曲单帽四方反棱柱的配位环境中被九个O原子包围。双核结构通过分子内N - H⋯O（硝酸根）氢键进一步稳定。
