Solution-Mediated Synthesis of a Three-Dimensional Zinc Phosphate in the Presence of a Monoamine
A new open-framework zinc phosphate of the formula [C2H5NH3]2[Zn2(HPO4)3], I, has been synthesized at 60 °C in a. THF-water medium in the presence of ethylamine. The structure consists of a. network of strictly alternating ZnO4 and PO4 tetrahedra forming 4- and 8-membered rings, which connect to form intersecting elliptical channels bound by 12- and 8-T atoms (T = Zn, P) along the c. and b axes, respectively. The amine molecule sits in the channel bound by 12-T atoms and the -OH group of the HPO4 unit protrudes into the 8-membered channel. An interesting feature of I is that it has a very low framework density. Crystal data: [C2H5NH3]2[Zn2(HPO4)3], monoclinic, C2/c (no. 15), a = 17.351 (4), b = 9.507(5), c = 9.806(5) Å, ? = 102.68(2)°, V=1578.3(1) Å3, Z = 4.
