Abstract

Complexes [Ag(L_N)₂]NO₃∙4H₂O(I) and [Ag(L_N,N)₂]NO₃·EtOH·H₂O(II), where L is monodentate (L_N) or bidentate (L_N,N) nopinane-annelated oxo-4,5-diazafluoren-9-one are synthesized. The crystal structures of solvatomorphs I and II are composed of [AgL₂]⁺ complex cations, nitrate anions, and H₂O and EtOH solvate molecules. In complex I, the Ag⁺ cation coordinates two N atoms of two monodentate L_N (c.n. = 2), and in the structure of II there are four N atoms of two bidentate cyclic L_N,N (c.n. = 4). The compounds are characterized by the elemental analysis, powder X-ray diffraction, and NMR spectroscopy. The electrochemical and luminescent properties of starting compound L and complex II are investigated.

银(I)与诺蒎烷-环结氧-4,5-重氮芴-9- 1配合物的晶体结构及其电化学和发光性能

合成了配合物[Ag(LN)2]NO3∙4H2O(I)和[Ag(LN，N)2]NO3·EtOH·H2O(II)，其中L为单齿（LN）或双齿（LN，N） no蒎烷-羰基-4,5-重氮芴-9- 1。溶剂型I和溶剂型II的晶体结构由[AgL2]+络合物阳离子、硝酸盐阴离子、H2O和EtOH溶剂化物分子组成。在配合物I中，Ag+阳离子配位两个单齿LN （c.n = 2）的两个N原子，在配合物II中，有两个双齿环状LN N （c.n = 4）的四个N原子。通过元素分析、粉末x射线衍射和核磁共振光谱对化合物进行了表征。研究了起始化合物L和配合物II的电化学和发光性质。
