- Fachbereich Chemie, Philipps-Universitaet Marburg, Hans-Meerwein-Strasse, D-35043 Marburg (Germany)
Two three-dimensional open-framework zinc phosphites, H{sub 2}aem.Zn{sub 3}(HPO{sub 3}){sub 4}.0.5H{sub 2}O (1) and H{sub 2}apm.Zn{sub 3}(HPO{sub 3}){sub 4} (2), have been synthesized by a phosphorous acid flux method, where aem=4-(2-aminoethyl)morpholine and apm=4-(3-aminopropyl)morpholine. Compound 1 crystallizes in the monoclinic system, P2{sub 1}/c, a=9.5852(7) A, b=20.3941(8) A, c=10.5339(8) A, beta=94.125(9){sup o}, V=2053.8(2) A{sup 3}, Z=4, R{sub 1}=0.0319, wR{sub 2}=0.0628. Compound 2 crystallizes in the monoclinic system, P2{sub 1}/n, a=8.589(2) A, b=14.020(3) A, c=16.606(3) A, beta=97.190(8){sup o}, V=1983.9(7) A{sup 3}, Z=4, R{sub 1}=0.0692, wR{sub 2}=0.1479. Both compounds are based on (3,4)-connected networks with 8- and 12-ring channels, which are constructed from Zn{sub 3}(HPO{sub 3}){sub 4} clusters as the same secondary building units. These inorganic clusters are spatially organized by different structure-directing agents into different three-dimensional frameworks. - Graphical abstract: Two three-dimensional open-framework zinc phosphites have been synthesized by a phosphorous acid flux method. The two compounds are constructed from Zn{sub 3}(HPO{sub 3}){sub 4} clusters and have noz and pcu topologies, respectively.
