| Popis: | Physicochemical properties of a new dihydrogenmonophosphate [2-NH 2 -6-CH 3 -C 4 H 3 N 2 O] 2 (H 2 PO 4 ) 2 are described on the basis of X-ray crystal structure investigation. This compound crystallizes in the triclinic space group P-1. The unit cell parameters are: a = 7.667(3) A, b = 8.204(5) A, c = 14.761(6) A, α = 98.85(4)°, β = 99.23(3)°, γ = 90.50(4)°, V = 905.0 A3, and Z = 2. The crystal structure was solved and refined to R = 0.037, using 4351 independent reflections. The atomic arrangement of this compound is built up by (H 2 PO 4 ) n n − chains. Each chain aggregates with organic molecules to form an open framework architecture through hydrogen bond interactions. The structure includes four types of hydrogen bonds. The first one, O─H─O, links the H 2 PO 4 groups to form (H 2 PO 4 ) n n − infinite inorganic chains parallel to the a axis. The three other types, O─H─O(carbonylic), N─H─O(carbonylic), and N─H─O, assemble the inorganic chains so as to build up a three-dimensional arrangement. This co... |
