The solution-mediated syntheses and single crystal structures of (CH3NH3)3·Zn40(AsO4)3 and (CH3NH3)3·Zn4O(P04)3 are reported. These compounds are built up from vertex-sharing three-dimensional Zn04 + AsO4/P04 tetrahedral frameworks encapsulating methylammonium cations in three-dimensional channel systems. These phases are closely related to the zeolite- like M3Zn4O(XO4)3·nH2O family of phases. Crystal data for (CH3NH3)3·Zn40(AsO4)3, M, = 790.47, monoclinic, space group P21 (No. 4), a = 7.814 (3)Å, b = 15.498 (6)Å, c = 7.815 (3) Å, {beta} = 92.91 (2)0, V = 945.1 (9) Å3, Z = 2, R(F) = 3.01%, RW(F) = 3.98% (2301 reflections, 236 parameters). Crystal data for (CH3NH3)3·Zn40(P04)3: M, = 658.63, monoclinic, space group P21 (No. 4), a = 7.6569 (5) Å, b = 15.241 (1)Å, c= 7.6589 (5) Å, {beta} = 92.740 (1)0, V= 892.7 (5) Å3, Z = 2, R(F)= 8.07%, RW(F)= 9.60% (2694 reflections, 106 parameters).
