摘要：

A new borophosphate Co-3(BPO4)(2)(PO4)(OH)(3) was synthesized by a conventional hydrothermal method. The titled compound crystallizes in the monoclinic system with space group Cc, which exhibits a typical spin-chain structure. In the structural framework, Co2+ ions form a zigzag chain via edge-sharing oxygen atoms, and further the zigzag Co-chains are separated by linear [B2P20O8](infinity) chains. Magnetic measurements confirm that Co-3(BPO4)(2)(PO4)(OH)(3) possesses an antiferromagnetic ordering at T-N = 12 K, while a 1/3 plateau is observed in the magnetization curve at 2 K. The possible spin arrangements for antiferromagnetic, ferrimagnetic, and ferromagnetic states are also suggested.
