以不加水为溶剂的磷酸（dah=1,7-二氨基庚烷，dab=1,4-二氨基丁烷）为溶剂，制备了新型三维开骨架亚磷酸锌和亚磷酸锰草酸盐H2dah·Zn3(HPO3)4(1)和H2dab·Mn2(HPO3)2(C2O4)(H2O)2(2)。化合物1由严格交替的zno4四面体和hpo3伪金字塔构成，具有沿[001]方向的12环之字形通道。化合物2由中性锰亚磷酸酯层组成，由草酸盐配体支撑形成具有沿[010]方向运行的12环通道的三维杂化框架。磁化率测量证明了2中存在反铁磁相互作用。晶体数据：1、正交，Pbcn, a=9.9096(8)Å， b=15.6780(6)Å， c=13.8022(6)Å， V=2144.3(2)Å3， Z=4；2、单斜,P21 / n = 5.616 (3) a, b = 15.431 (3) a, c = 9.445(3),β= 91.72(2)°,V = 818.2 (5) A3, Z = 2。
New three-dimensional open-framework zinc phosphite and manganese phosphite-oxalate, H2dah·Zn3(HPO3)4(1) and H2dab·Mn2(HPO3)2(C2O4)(H2O)2(2), were prepared in a flux of phosphorous acid without the addition of water as a solvent (dah=1,7-diaminoheptane, dab=1,4-diaminobutane). Compound 1 is constructed from strictly alternating ZnO4tetrahedra and HPO3pseudo pyramids, and has zigzag 12-ring channels running along the [001] direction. Compound 2 consists of neutral manganese phosphites layers, which are pillared by oxalate ligands to form a three-dimensional hybrid framework with 12-ring channels running along the [010] direction. Magnetic susceptibility measurements demonstrate the existence of antiferromagnetic interaction in 2. Crystal data: 1, orthorhombic, Pbcn, a=9.9096(8)Å, b=15.6780(6)Å, c=13.8022(6)Å, V=2144.3(2)Å3, Z=4; 2, monoclinic, P21/n, a=5.616(3)Å, b=15.431(3)Å, c=9.445(3)Å, β=91.72(2)°, V=818.2(5)Å3, Z=2.
