In the title 1:1 silver(I) 4-carb-oxy-pyridine-3-carboxyl-ate adduct with triphenyl-phosphine, Ag(C(7)H(4)NO(4))(C(18)H(15)P), the carboxyl-ate anion bridges the phosphine-coordinated Ag atoms through its N and O atoms, generating a coordination polymer forming layers in the bc plane. The Ag atom exists in a distorted tetra-hedral geometry. The H atom of the carboxyl-ate is midway between two O atoms of the two carboxyl groups, thus forming a strong intra-molecular hydrogen bond.
标题为1:1的4-羧基吡啶-3-羧酸盐银(I)与三苯基膦加合物,即[Ag(C₇H₄NO₄)(C₁₈H₁₅P)]ₙ,羧酸根阴离子通过其N和O原子桥连膦配位的Ag原子,形成一种配位聚合物,在bc平面上形成层状结构。Ag原子以扭曲的四面体几何构型存在。羧酸根的H原子位于两个羧基的两个O原子之间的中间位置,从而形成一个强的分子内氢键。
