| Abstract: | A novel
organically templated cobalt phosphate supramolecule, [Co(H2O)6]2[HPO4]4·2(C2N2H10),
has been synthesized hydro-thermally and characterized by single crystal X-ray
diffraction, vibrational spectroscopy, elemental analysis and TGA-DSC. The
title compound crystallizes in monoclinic system, space group P2(1)/c, a = 6.27(3) Å, b = 16.367(8) Å, c = 14.736(7) Å,
α = 90.00°, β = 91.405(7)°, γ = 90.00°, V
= 1512.2(3) Å3, Z = 2.
The structure of the title compound consists of four isolated PO3(OH)
tetrahedrons, two cobalt complex cation [Co(H2O)6]2+
and two diprotonated ethylenediamine molecules. The PO3(OH)
tetrahedrons and cobalt octahedras are linked together via hydrogen bonding
interaction, forming an open framework architecture. Protonated
ethylenediamine molecules reside in the spacing of the framework and compensate
the charge balance. |
