Low dimensional quantum magnets have been extensively investigated recently because of their novel intriguing quantum phenomena such as spin liquid and spin-charge separation, and their relation to high temperature superconductivity.[1] However, experimental realization of such low dimensional quantum magnets is still difficult, in particular experimentally realizing the specific magnetic lattices and models such as one dimensional (1D) chain lattice and two dimensional (2D) triangular lattice and Kagomé lattice, which have been theoretically predicted and investigated. Thus, discovery of experimental magnetic lattices is crucial to test theoretical predictions or to explore novel exotic phenomena. In this talk, experimental realization and magnetic properties of several new low dimensional quantum antiferromagnets with specific magnetic lattices will be introduced, including the nearly-ideal 1D spin chain systems (2,2’-bipyridyl)FeF₃·2H₂O with S = 5/2 and MF₂(bibp)₂ (bibp = 4,4’-bis(1-imidazolyl)biphenyl) (M = Co, S = 3/2, Ni, S = 1), 1D zig-zag chain systems MIO₃F (M = Ni, Co) with spin-flop transition,[2] 1D mixed-spin chain systems MVF₆(pyrazine)₂·4H₂O with constrast magnetic behaviors, 2D triangular systems KMB₄O₆F₃ (M = Co, Ni, Fe) and Ni(HPO₃)(4,4’-bipyridyl)H₂O, 2D Kagomé systems M₃(PO₃)(4,4’-bipyridyl)₃(H₂O)₆·4H₂O.
