A new transition metal-antimony oxo-cluster based compound has been synthesized in water under room temperature.Its formula is Na_(6)[Cu_(6)MnSb_(6)(μ_(3)-OH)_(2)(OH)(μ_(4)-O)_(6)(tartrate)_(6)]-_(2)0H_(2)O(1),where...A new transition metal-antimony oxo-cluster based compound has been synthesized in water under room temperature.Its formula is Na_(6)[Cu_(6)MnSb_(6)(μ_(3)-OH)_(2)(OH)(μ_(4)-O)_(6)(tartrate)_(6)]-_(2)0H_(2)O(1),where tartrate represents rac-tartaric acid.It was characterized by elemental analysis,infrared spectrum and X-ray single-crystal diffraction.The compound crystallizes in the monoclinic system,space group P2_(1/n).Structural analyses revealed that two Sb_(3)(μ_(3)-0)(tartrate)_(3)scaffolds sandwich a Cu^(Ⅱ)_(_(6))Mn^(Ⅲ)middle layer to form the cluster.In the middle layer,all the seven metal ions lie in an almost regular hexagon,with Mn^(Ⅲ)ion in the center and six Cu^(Ⅱ)ions along the edges of the hexagon.As a 4-connected node,each cluster is interlinked to its nearest four{Cu_(6)Mn}neighbors through Na^(+),generating a 3D supramolecular framework.The temperature-dependent magnetic susceptibilities indicated dominating antiferromagnetic interactions in 1 with J_(Cu-Cu)=176.34 and J(Cu-Mn)=-14.44 cm^(-1).展开更多
