Two new three-dimensional open-framework zinc phosphites, (H2aep)2·Zn6(HPO3)8(1) and H3taea·Zn3(HPO3)4.5(2) have been synthesized by the H3PO3flux method, where aep=1-(2-aminoethyl)piperazine and taea=tris(2-aminoethyl)amine. Compound 1 has a 3,4-connected framework with (4,6,8) sheets connected by corner-sharing 4-ring chains. Compound 2 has 3-connected sheets built from quintuple-fused 4-rings, which are further linked by HPO3units to form the three-dimensional structure. The presence of large 16-ring channels in the two structures is noteworthy. Crystal data: 1, monoclinic, P21/c, a=18.8613(7)Å, b=9.0856(5)Å, c=24.9485(8)Å, β=107.211(6)°, V=4083.9(3)Å3, Z=4, R1=0.0457, wR2=0.1050; 2, monoclinic, C2/c, a=28.911(2)Å, b=8.302(3)Å, c=19.513(3)Å, β=103.715(16)°, V=4549.8(17)Å3, Z=4, R1=0.0428, wR2=0.1165.
