A Novel Three-dimensional Framework with Tunnels Based on the Cobalt-containing Molybdenum Phosphate Moieties

【Abstract】 A novel compound (H 2en) 5[CoMo 12 O 50 P 8(OH) 12 ]·2H 2O (1) (en =H 2NCH 2CH 2NH 2) has been hydrothermally synthesized and characterized by elemental analyses, IR, EPR, XPS spectra and single crystal X ray diffraction analyses. Compound 1 crystallizes in a triclinic system, space group P ī, with a =1 1863(2) nm, b =1 3361(3) nm, c =1 3783(3) nm, α = 88 13(3)°, β =70 09(3)°, γ =65 24(3)°, V =1 8497(6) nm 3, and R =0 0417. The basic building blocks of compound 1 are {Mo 6P 4} clusters forming dimers through the {CoO 6} octahedra. Compound 1 exhibits an unusual three dimensional framework with tunnels owing to the extensive hydrogen bonding interactions between the dimers and H 2en.更多还原
