Abstract
The reaction of amine phosphates with metal ions, under mild conditions, has been utilized for the synthesis of open-framework phosphates. Two new amine phosphates, DABCO-phosphate and imidazole-phosphate, synthesized for the first time, were employed for this purpose. Thus, DABCO-phosphate reacts with Co(II) and Zn(II) ions giving rise to open-framework structures, of which [C6N2H14][Co2(HPO4)3, I, is a new 3-dimensional structure. Reaction of imidazole phosphate with Zn(II) ions gave a new phosphate, II, [C3N2H6] [Zn4(OH)((PO4)3]. Both I and II have linkages involving MO4 (M=Co, Zn) and PO4 tetrahedra giving rise to three-dimensional structures. While I has two distinct channels along the crystallographic directions, II possesses only one-dimensional channels along with one-dimensional infinite Zn---O---Zn chains.
