A new anionic coordination complex of Zn(II) containing the highly pre-organized ligand 1,10-phenanthroline-2,9-dicarboxylate (PDA), (H3O)(2)[Zn(PDA)(2)]center dot 2CH(3)NO(2)center dot 2H(2)O center dot(1), has been synthesized by solvothermal methods and characterized by elemental analysis, infrared spectroscopy and single crystal X-ray diffraction. The last of these techniques revealed a coordination sphere around Zn(ll) consisting of four N atoms and four O donors from two 1,10-phenanthroline-2,9-dicarboxylate ligands which features a distorted dodecahedral geometry. The ionic coordination motifs in 1 are held together by intermolecular O-H center dot center dot center dot O, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonding, C-H center dot center dot center dot pi and pi-pi stacking interactions, to produce an extended 2D architecture.
