trans-Diaqua­bis­[5-carb­oxy-4-carboxyl­ato-2-(4-pyridinio)-1H-imidazol-1-ido-κ(2) N (3),O (4)]zinc(II)

In the title complex, [Zn(C(10)H(6)N(3)O(4))(2)(H(2)O)(2)], the Zn(II) atom is located on a twofold rotation axis and is coordinated by two trans-positioned N,O-bidentate and zwitterionic 5-carb­oxy-4-carboxyl­ato-2-(4-pyridinio)-1H-imidazol-1-ide (H(2)PIDC(−)) ligands and two water mol­ecules, defi...

Descripción
Sumario:In the title complex, [Zn(C(10)H(6)N(3)O(4))(2)(H(2)O)(2)], the Zn(II) atom is located on a twofold rotation axis and is coordinated by two trans-positioned N,O-bidentate and zwitterionic 5-carb­oxy-4-carboxyl­ato-2-(4-pyridinio)-1H-imidazol-1-ide (H(2)PIDC(−)) ligands and two water mol­ecules, defining a distorted octa­hedral environment. The complete solid-state structure can be described as a three-dimensional supra­molecular framework, stabilized by extensive hydrogen-bonding inter­actions involving the coordinated water mol­ecules, uncoordin­ated imidazole N atom, protonated pyridine N and carboxyl­ate O atoms of the H(2)PIDC(−) ligands.
