Abstract
Abstract The solution-mediated syntheses, single-crystal structures, and some physical properties of the first 1,3-diammonium-propane zinc phosphates, H3N(CH2)3NH3·Zn2(HPO4)2(H2PO4)2and H3N(CH2)3NH3·Zn(HPO4)2, are described. Both phases contain vertex-sharing ZnO4and (H2/H)PO4tetrahedra, accompanied by doubly protonated organic cations. H3N(CH2)3NH3·Zn2(HPO4)2(H2PO4)2consists of a layered motif of infinite sheets of tetrahedral 12-rings, whereas H3N(CH2)3NH3·Zn(HPO4)2is strongly one-dimensional and consists of tetrahedral 4-ring “ladders.” Crystal data: H3N(CH2)3NH3·Zn2(HPO4)2(H2PO4)2,Mr=590.82, monoclinic, space groupP21/a(No. 14),a=15.056(2) A,b=7.8454(8) A,c=16.344(2) A,β=115.469(8)°,V=1742.9(3) A3,Z=4,R(F)=5.17%,Rw(F)=5.68% [2859 observed reflections withI=3σ(I)]; H3N(CH2)3NH3·Zn(HPO4)2,Mr=333.48, orthorhombic, space groupP212121(No. 19),a=5.2206(7) A,b=12.717(2) A,c=15.570(2) A,V=1033.7(3) A3,Z=4,R(F)=4.16%,Rw(F)=3.75% [1491 observed reflections withI>3σ(I)].
