Hydrothermal Synthesis and Crystal Structure of a New a-Keggin Unit-supported Cobalt Bipyridyl Complex: [Co(2,2'-BIPY)3]1.5[SiW12O40Co(2,2'-bipy)2(H2O)]·0.5H2O

A new α-Keggin unit-supported transition metal complex [Co(2,2′-bipy) 3 ] 1.5 [SiW 12 O 40 Co(2,2′-bipy) 2 -(H 2 O)]·0.5H 2 O has been hydrothermally synthesized and characterized by X-ray crystallography, showing that [Co(2,2′-bipy) 2 (H 2 O)] 2+ units are covalently bonded to the α-Keggin cluster...

Description
Summary:A new α-Keggin unit-supported transition metal complex [Co(2,2′-bipy) 3 ] 1.5 [SiW 12 O 40 Co(2,2′-bipy) 2 -(H 2 O)]·0.5H 2 O has been hydrothermally synthesized and characterized by X-ray crystallography, showing that [Co(2,2′-bipy) 2 (H 2 O)] 2+ units are covalently bonded to the α-Keggin cluster [SiW V W VI 11 O 50 ] 5− . Intermolecular hydrogen bonding interactions and short O ... O contacts force the structure into an interesting one-dimensional supramolecular array. Crystals are monoclinic space group C2/c, with a = 46.676(9), b = 14.348(3), c = 26.010(5) Å, β = 90.33(3)°, V = 17419(6) Å 3 , Z = 8.
