✦ Synopsis

An organic+inorganic hybrid solid, (Cu(2,2-bpy) 2 ) 2 Mo 8 O 26 , has been hydrothermally synthesized and structurally characterized by single-crystal X-ray di4raction. Dark green crystals crystallize in the orthorhombic system, space group Pna21, a ‫؍‬ 24.164(5), b ‫؍‬ 18.281(4), c ‫؍‬ 11.877(2) A > , ‫؍‬ 903, ‫؍‬ 903, ‫؍‬ 903, V ‫؍‬ 5247(2) A > 3 , Z ‫؍‬ 4, (MoK ) ‫؍‬ 0.71073 A > (R(F) ‫؍‬ 0.0331 for 5353 re6ections). Data were collected on a Siemens P4 four-circle di4ractometer at 293 K in the range 1.693 < < 25.043 using the -scan technique. The structure was solved by the direct method and re5ned by full-matrix least squares on F 2 using SHELXL-93. The structure of this compound consists of discrete (Cu(2,2-bpy) 2 ) 2 Mo 8 O 26 clusters, constructed from -octamolybdate subunits ((Mo 8 O 26 ) 4؊ ) covalently bonded to two (Cu(2,2-bpy) 2 ) 2؉ coordination complexes via bridging oxo groups that connect two adjacent molybdenum sites.
