A new linear chain compound, [Cu(en)2][Cu(en)2(H2O)1.5][Cu(en)2(H2O)2]0.5[{Cu(en)2}5{HP2Mo5O23}3]∙ 6.5H2O (1) (en = ethylenediamine), has been synthesized under mild hydrothermal conditions, and characterized by elemental analysis, IR, thermogravimetric analyses, magnetic susceptibility measurements and single-crystal X-ray diffraction. The crystals are monoclinic, C2/c, a = 42.509(2) Å, b = 25.542(2) Å, c =22.1011(14) Å, β = 102.5940(10)º, V = 23419(3) Å3, Z = 8. The crystal structure of (1) features Cu-bearing cations that are both free as well as being coordinated to the poly(oxomolybdophosphate) groups formed a linear chain that runs along the b axis. Magnetic studies show that the complex is antiferromagnetic.
