Abstract:
The crystal structure of [C10N2H10][ZnCl(HPO4)]2 contains corrugated tetrahedral layers equation image with 63 topology. Charge balance is achieved by insertion of diprotonated 4,4′-bipyridine between the layers. Crystal data: monoclinic, P21/n (no. 14), a = 4.8832(2) Å, b = 22.673(2) Å, c = 8.1643(4) Å, β = 104.02(1)°; V = 877.0(1) Å3; Z = 4; R1 = 0.041 and wR2 = 0.088 for 1836 reflections [I > 2σ(I)]. Tetrahedral layers equation image are also observed in other organo-ammonium templated compounds. However, their topologies are characterized by 4.82 nets. With the title compound a layered tetrahedral net equation image with 63-topology is reported for the first time.
