Abstract

In the title compound, {[Mn(C(14)H(16)N(5)O(3))(2)]·2H(2)O}(n), the Mn(II) atom (site symmetry ) exhibits a distorted trans-MnN(2)O(4) octa-hedral geometry defined by two monodentate N-bonded and two bidentate O,O'-bonded 8-ethyl-5-oxo-2-(piperazin-1-yl)-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxyl-ate anions. An N-H⋯O hydrogen bond is present in the crystal structure. The extended two-dimensional structure is a square grid and the disordered uncoordinated water mol-ecules occupy cavities within the grid.

摘要

在标题化合物{[Mn(C₁₄H₁₆N₅O₃)₂]·2H₂O}ₙ中，Mn(II)原子（位点对称性）呈现出一种扭曲的反式MnN₂O₄八面体几何构型，由两个单齿N键合和两个双齿O,O'-键合的8-乙基-5-氧代-2-(哌嗪-1-基)-5,8-二氢吡啶并[2,3-d]嘧啶-6-羧酸根阴离子所定义。晶体结构中存在一个N-H⋯O氢键。扩展的二维结构是一个方格，无序的未配位水分子占据方格内的空穴。
