- Abstract
The polyoxotungstate (C4H10ON)9H3[Mn2Na2(C4H10ON)2(GeW9O34)2] ·9H2O ( 1) was synthesized in aqueous solution and characterized by single-crystal and powder X-ray diffraction, IR spectroscopy, TGA, and variable temperature susceptibility measurements. The polyoxoanion framework of 1 is built on the lacunary Keggin-type polyanion [GeW9O34]10-. The central core shows [Mn2Na2(μ4-O)2(μ3-O)6(μ2-O)8(C4H10ON)2] where the morpholine molecule is bound to the Na+ ion. The polyanions of 1 are further bridged into a one-dimensional (1D) chain by the hydrogen bonding interactions. The magnetic investigations demonstrate the presence of antiferromagnetic exchange interactions for 1.
