Two new open‐framework zincophosphites, Zn(H 6 C 4 N 2 S)(HPO 3 ) (TJPU‐4) and [C 6 N 2 H 14 ]·[Zn 3 (HPO 3 ) 4 ] (TJPU‐5) have been hydrothermally synthesized by using 2‐mercapto‐1‐methylimidazole [MMI] and 1,4‐diazabicyclo[2.2.2]octane [DABCO] as templates. TJPU‐4 crystallizes in monoclinic space group P 2 1 /c with the cell parameters a = 8.787(4) Å, b = 9.732(4) Å, c = 10.515(4) Å, β = 105.316(6)°, V = 867.3(6) Å 3 . The structure of TJPU‐4 is constructed by ZnO 3 S tetrahedron and HPO 3 pseudo‐pyramid to generate a layer of 4, 8‐network in bc plane. The organic template locates on the both sides of the 8‐membered rings and bonds to zinc atom through Zn–S bond. TJPU‐5 crystallizes in the triclinic space group $P{\bar 1}$ with cell parameters a = 9.294 (5) Å, b = 9.976 (5) Å, c = 9.986 (5) Å, α = 85.692 (7)°, β = 82.010 (7)° and γ = 80.184 (7)°, V = 902.1 (8) Å 3 . A novel 4 4 8 8 cage is found in TJPU‐5. The connections of Zn(1)O 4 , Zn(3)O 4 and HPO 3 groups give rise to an infinite corner‐shared four‐ring chain. Using Zn(2)O 4 as four connected bridges, linkages of these chains produce a 3‐D framework with intersecting 8‐ring channels running along [100], [010], [001], [011] and [111] directions.
