Abstract

The syntheses and structures of C2H7N4O⋅ZnCl(HPO4) and (C2H7N4O)2⋅Zn3(H2O)(HPO3)4 are reported. Both phases arose in solution mediated reactions by way of the controlled, in situ, preparation of the cationic [C2H7N4O]+ guanylurea template by the slow hydrolysis of the neutral 2-cyanoguanidine starting material. C2H7N4O⋅ZnCl(HPO4) contains anionic [ZnCl(HPO4)] 63-topology polyhedral layers built up from vertex-sharing ZnO3Cl and HPO4 polyhedra. (C2H7N4O)2⋅Zn3(H2O)(HPO3)4 is also layered and contains ZnO4, ZnO3(H2O) and HPO3 polyhedra sharing vertices by way of ZnOP bonds. In both structures, the guanylurea template participates in numerous template-to-framework and also template-to-template hydrogen bonds. Strikingly, the arrangement of template-to-template H bonds is different in the two structures, and also different to that seen earlier in C2H7N4O⋅ZnPO4.
