Structure and Magnetic Properties of Pb2Cu3B4O11: a New Copper Borate Featuring [Cu3O8]10- Units
Pb2Cu3B4O11 crystallizes in the monoclinic space group P2/n (No. 13) with a = 6.8016(15) Å, b = 4.7123(10) Å, c = 14.614(3) Å, β = 97.089(3)°, and Z = 2. The crystal structure consists of infinite [Cu3O8]10- zigzag chains of alternating dimers and monomers. The magnetic susceptibility and specific h...

Summary: | Pb2Cu3B4O11 crystallizes in the monoclinic space group P2/n (No. 13) with a = 6.8016(15) Å, b = 4.7123(10) Å, c = 14.614(3) Å, β = 97.089(3)°, and Z = 2. The crystal structure consists of infinite [Cu3O8]10- zigzag chains of alternating dimers and monomers. The magnetic susceptibility and specific heat capacity show spin-gap and Curie−Weiss behaviors that can be explained by a model of Cu(2)−Cu(2) dimers and isolated or weakly coupled Cu(1) monomers. |
