This compound has one-dimensional anionic chains containing four-membered rings built from corner-sharing linked alternating ZnO4 tetrahedra and HPO3 pseudo pyramids. The zinc hydrogen phosphite chains are interacted with the templates of diprotonated piperazine by N—H…O hydrogen bond.

It crystallizes in the monoclinic space group C2/c with unit cell parameters: a=1.992 1(4) nm, b=0.374 96(7) nm, c=1.930 3(4) nm, β=109.21(3)°. V=1.361 6(5) nm3, Z=4, R=0.034 9, wR=0.084 4. The Ca atom is eight-coordinated by four O atoms from different p-pyridone ligands and four O atoms from two chelating nitrate anions, and displays a distorted square pyramidal coordination geometry. Each p-pyridone ligand bridges two adjacent Ca atoms, forming a infinite chain along the b direction. The Ca...Ca distance is 0.374 96(7) nm. A layer structure is further constructed by intermolecular hydrogen bonds and π-π interactions. The result of TG analysis shows that the title complex is stable under 185 ℃. CCDC: 241576.展开更多
