The crystal structure of the title compound, [Ni(CHN)(NO)]NO, at room temperature, has monoclinic (2/) symmetry. The structure displays inter-molecular hydrogen bonding. The nickel displays a distorted bipyramidal geometry with the symmetric bidentate bonded nitrate occupying an equatorial site. The 1,4,7,10-tetra-aza-cyclo-dodecane (cyclen) backbone has the [4,8] configuration, with three nitro-gen-bound H atoms directed above the plane of the nitro-gen atoms towards the offset nickel atom with the fourth nitro-gen-bound hydrogen directed below from the plane of the nitro-gen atoms. The nitrate anion O atoms are seen to hydrogen bond to the H atoms bound to the N atoms of the ligand.
标题化合物[Ni(CHN)(NO)]NO在室温下的晶体结构具有单斜(2/)对称性。该结构显示出分子间氢键。镍呈现出扭曲的双锥几何构型,对称双齿键合的硝酸根占据一个赤道位置。1,4,7,10 - 四氮杂环十二烷(环烯)主链具有[4,8]构型,三个与氮相连的氢原子指向氮原子平面上方朝向偏移的镍原子,而第四个与氮相连的氢原子指向氮原子平面下方。硝酸根阴离子的氧原子与配体中与氮原子相连的氢原子形成氢键。
