In the title compound, a new macrocyclic metal complex, [Ag(NO(3))(C(21)H(15)N(3)O(4))], all non-H atoms are in a close-to-planar geometry (except for the nitrate anion), with a maximum out-of-plane deviation of 0.327 (6) Å for a pyridine C atom. The dihedral angle between the least-squares plane through the [3,3'-dihy-droxy-3,3'-bis-(pyridin-3-yl)-1,1'-(pyridine-2,6-di-yl)dipropan-1-one]silver(I) fragment and the nitrate anion is 31.29 (13)°. The mol-ecular structure is stabilized by several inter- and intra-molecular O-H⋯O and C-H⋯O hydrogen bonds. The Ag(I) atom is coordinated by two pyridine N atoms and two O atoms of the nitrate anion in a geometry intermediate between tetrahedral and square-planar.
在标题化合物[Ag(NO₃)(C₂₁H₁₅N₃O₄)]（一种新型大环金属配合物）中，除硝酸根阴离子外，所有非氢原子都处于接近平面的几何构型，吡啶环上的一个碳原子的最大平面外偏差为0.327(6) Å。通过[3,3'-二羟基-3,3'-双(吡啶-3-基)-1,1'-(吡啶-2,6-二基)二丙-1-酮]银(I)片段的最小二乘平面与硝酸根阴离子之间的二面角为31.29(13)°。分子结构通过多个分子间和分子内的O-H⋯O和C-H⋯O氢键得以稳定。Ag(I)原子由两个吡啶N原子和硝酸根阴离子的两个O原子配位，其几何构型介于四面体和平面正方形之间。
