4个新的同/异三核金属有机骨架，分别为：{[NH2(CH3)2]2[Co3(FDA)4(CH3OH)2]}n(1)，{[NH2(CH3)2]2[Co3(FDA)4]·2DMF}n(2)，{[Gd2Co(FDA)4(H2O)4]·2H2O}n(3)，{[Dy2Co(FDA)4(乙二醇)2]·2H2O}n(4)(FDA=呋喃-2，5-二元酸)，在溶剂热条件下得到，并用单晶X射线衍射、磁化率和发光测量对其进行了表征。四种MOF的构筑基团都是由羧基稳定的线性三核簇合物，但其三维结构有所不同。MOF 1和2都是点符号为(412.63)的PCU网，而MOF 3和4分别展示了点符号为(418.624.83)(43)2和(43)2(46.618.84)的3，10T9和tfz-d网。磁化率测量表明，1-3中存在反铁磁相互作用，而4中Co(II)和Dy(III)离子之间存在有趣的铁磁相互作用。发光研究...
Four new homo- and heterometallic metal–organic frameworks (MOFs) based on linear homo/heterotrinuclear nodes, namely, {[NH2(CH3)2]2[Co3(FDA)4(CH3OH)2]}n (1), {[NH2(CH3)2]2[Co3(FDA)4]·2DMF}n (2), {[Gd2Co(FDA)4(H2O)4]·2H2O}n (3), and {[Dy2Co(FDA)4(glycol)2]·2H2O}n (4) (H2FDA = furan-2,5-dicarboxylic acid), were obtained under solvothermal conditions and characterized by single crystal X-ray diffraction, magnetic susceptibility, and luminescence measurements. The building blocks of four MOFs are linear trinuclear clusters stabilized by carboxylic groups, but the three-dimensional frameworks are different. MOFs 1 and 2 are both pcu nets with a point symbol of (412.63), whereas MOFs 3 and 4 exhibit 3,10T9 and tfz-d nets with the point symbols of (418.624.83)(43)2 and (43)2(46.618.84), respectively. Magnetic susceptibility measurements indicate that there are antiferromagnetic interactions in 1–3, while 4 displays interesting ferromagnetic interactions between Co(II) and Dy(III) ions. Luminescence investigatio...
