收藏资源简介：
The syntheses, crystal structures, and properties of C4N3OH7·ZnHPO3, C4N3OH7·Zn(H2O)HPO3, and (C4N3OH7)2·ZnHPO3·H2O are reported. These new creatinine zinc phosphites are built up from networks of vertex-sharing HPO3 pseudopyramids and various types of ZnO2N2, ZnO3N, and ZnO2N(H2O) tetrahedra, resulting in extended structures of different dimensionalities (as sheets, clusters, and chains, respectively). They demonstrate the structural effect of incorporating “terminal” (nonnetworking) Zn−N and Zn−OH2 moieties into zinc centers. Crystal data: C4N3OH7·ZnHPO3, triclinic, P1̄ (No. 2), a = 8.9351(4) Å, b = 9.5011(4) Å, c = 9.9806(4) Å, α = 87.451(1)°, β = 85.686(1)°, γ = 89.551(1)°, Z = 4; C4N3OH7·Zn(H2O)HPO3, monoclinic, P21/c (No. 14), a = 10.1198(7) Å, b = 7.2996(5) Å, c = 13.7421(9) Å, β = 107.522(1)°, Z = 4; (C4N3OH7)2·ZnHPO3·H2O, triclinic, P1̄ (No. 2), a = 10.7289(6) Å, b = 10.9051(6)Å, c = 13.9881(8) Å, α = 89.508(1)°, β = 74.995(1)°, γ = 74.932(1)°, Z = 4.
