Hydrothermal Synthesis, Crystal Structure, Magnetic Properties and Network Topology of a Novel Binuclear Co(Ⅱ) Coordination Polymer ∞1[Co2(4,4'-bpy)2(L)4] (bpy=Bipyridine, HL=2-Fluorbenzoic Acid)
摘要:
One novel binuclear Co(Ⅱ) coordination polymer ∞1[Co2(4,4'-bpy)2(L)4] (1, bpy=bipyridine, HL=2-fluorbenzoic acid) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR and X-ray single-crystal diffraction. Complex 1 crystallizes in the monoclinic system, space group P21/c with a=11.163(2), b=21.943(4), c=9.6381(19) Å, β=113.92(3)°, V=2158.2(7) Å3, Z=4, Dc=1.518 g/cm3, Mr=493.31, F(000)=1004, R=0.0303 and wR=0.0808 for 3614 observed reflections (I>2σ(I)). Complex 1 exhibits a 3D Schlafli symbol (4.62)(4.66.83) topological framework, and the magnetic characterization shows weak antiferromagnetic coupling exchange between two Co ions.
