Abstract
AbstractA new organically templated nickel–zinc phosphate, [C2N2H10]·[Ni2.4Zn3.6(PO4)4(HPO4)]·H2O, has been synthesized from an aqueous solution containing NiCl2·6H2O, Zn(OAc)2·2H2O, H3PO4 and ethylenediamine as the structure‐directing agent. The compound crystallizes in the monoclinic system, space group C2/c (No. 15), a = 19.1563(5), b = 5.0316(2), c = 21.1724(5) Å, α = 103.201(3)°, V = 1986.81(11) Å3, Z = 4. It possesses a three‐dimensional framework constructed from MO4 (M = Ni, Zn), PO4, and HPO4 tetrahedra through their vertices. One‐dimensional 8‐ring channels are found in the structure, with the diprotonated organic templates residing in the tunnels and interacting with the inorganic framework by extensive hydrogen bonds. The framework is characterized by infinite helical chains of corner‐sharing MO4 (M = Ni, Zn) tetrahedra.
