A novel compound (H 2 en) 5 [CoMo 12 O 50 P 8 (OH) 12 ] ·2H 2 O (1) (en = H 2 NCH 2 CH 2 NH 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 Pi , with a = 1.1863(2) nm, b = 1.3361(3) nm, c = 1.3783(3) nm, a = 88.13(3)°, β = 70.09(3)°, γ = 65.24(3)°, V = 1.8497(6) mn 3 , and R = 0.0417. The basic building blocks of compound 1 are|Mo 6 P 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 2 en.
