It crystallizes in the orthorhombic system with space group Pnma（No. 62） and features a 3D architecture built up of adjacent zig-zag linear structures of [CoP4O（16）]∞ along [100], and further connected by [Bi2O（11）] dimers to form a 3D framework, where the Ba2＋ are located in the free space. The stereochemical activity of the Bi3＋ lone pair has also been discussed. The result of magnetic property measurement confirms the antiferromagnetic property of Ba2Bi2Co（PO4）4.展开更多
