A new linear chain compound, [Cu(en) 2 ][Cu(en) 2 (H 2 O) 1.5 ][Cu(en) 2 (H 2 O) 2 ] 0.5 [{Cu(en) 2 } 5 {HP 2 Mo 5 O 23 } 3 ] · 6.5H 2 O ( 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) Å 3 , 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. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
