dc.description.abstract A 4-membered ring zinc phosphate monomer, I, [C6N2H18](2+) [Zn(HPO4) (H2PO4)(2)](2-), has been isolated by the reaction of the Zn2+ with the amine, N,N,N',N'-tetramethylethylenediamine (TMED) and H3PO4 at room temperature over an extended period of time, It could also be prepared by the reaction of the amine phosphate, [C6N2H18][HPO4] 2H(2)O, with Zn2+ in the temperature range 30-80 degrees C. The phosphate monomer consists of a network of ZnO4, PO2(OH)(2), and PO3(OH) tetrahedral units linked by their vertices, forming isolated 4-membered rings that are held by hydrogen bond interactions. Interestingly, I, on mild heating, transform into a layered structure, II, [C6N2H18](2+) [Zn-3(H2O)(4)(HPO4)(4)](2-). The structure of II consists of a network of ZnO4, ZnO2(H2O)(4), and PO3(OH) moieties sharing the vertices, forming a layered architecture. The formation of a layered structure from the 4-membered ring monomer suggests that the 4-membered ring is likely to be the primary building unit of the open-framework phosphates.
