摘要：A novel two-dimensional layered Fe^Ⅲformate,Fe(HCO2)2ClH2O,has been synthesized by solvothermal reaction.The structure of complex is characterized by single-crystal X-ray diffraction.The complex crystallizes in tetragonal space group P4/nmm with a=5.9588(6),c=8.3831(17)Å,V=297.66(7)Å3,Z=2,F(000)=198,Dc=2.224 g/cm3,Mr=199.35,μ=2.927 mm−1,the final R=0.0231 and wR=0.0585(I>2σ(I))for all data.Single-crystal structure analysis indicates that the complex has a 2D metal formate structure with only formate anions as bridges.The anti-anti formats link the Fe^Ⅲions to form a(4,4)net,while the chlorine ions and water molecules coordinate to Fe^Ⅲon both sides of the layer.Magnetic study have shown that an antiferromagnetic interactions between the Fe&ions in the complex.And a field induced spin-flop was detected at low temperature.
