[H3N(CH2)(3)NH3]center dot Be-3(HPO4)(4), a three-dimensional framework beryllophosphate containing tetrahedral 10-rings and 12-rings

The solution-mediated synthesis and single crystal structure of [H3N(CH2)(3 )NH3]. Be-3(HPO4)(4) are reported. This phase is built up from vertex-linke d BeO4 and HPO4 building units encapsulating the extra-framework 1,3-diammo nium propane cations. A new type of three-dimensional network containing 4- , 6-, 8-, 10-, and 12-rings results for the inorganic framework. The struct ure is stabilised by template-to-framework and framework-to-framework hydro gen bonding networks. Crystal data: [H3N(CH2)(3)NH3]. Be-3(HPO4)(4), M= 487 .10, monoclinic, space group P2(1)/n (No. 14). a=7.4219 (3) Angstrom. b=31. 5289 (14) Angstrom, c=13.6682 (6) Angstrom. beta =91.807 (I)degrees, V=3196 .8 Angstrom (3) Z=8, T=298 (2) K, R(F)=0.053, wR(F)=0.049.
