异烟酸（Hina）和半戊酸（H3hma）与镧系氧化物和卤化铜水热反应得到了10种具有3种结构类型的三维柱状层3D -4f异质金属配位聚合物（HCPs）。他们制定[Ln2Cu2(μ2 X)(协会)(ina) 4 (H2O) 2] n·2 nH2O (Ln =洛杉矶,X = Cl(我),Ln =洛杉矶,X = Br (I b), Ln =洛杉矶,X =我(我),Ln = Nd, X = Cl(我),Ln = Nd, X = Br (exp)], [Ln3Cu4.5I3.5(μ3-OH)(协会)(ina) 6 (H2O)] n·nH2O (Ln =公关(二世),Nd (II-B)],和[LnCu0.5(协会)(ina) (H2O)] n·nH2O (Ln = La (III-A)、Ce (III-B),公关(III-C)]。所有的hcp都用单晶x射线衍射进行了表征。在I型结构中，ln -有机层由卤化物桥接的双核[Cu2(μ2-Cl)(ina)4]单元通过Ln-O键支撑。在II型结构中，ln -有机层由两种不同的单价Cu基构建单元支撑，即无卤化物[Cu(ina)2]和含卤化物[Cu8(μ3-I)6(μ4-I)(ina)10]n。在III型结构中，波浪形异质金属C…
Hydrothermal reactions of isonicotinic acid (Hina) and hemimellitic acid (H3hma) with lanthanide oxides and copper halides yielded 10 three-dimensional (3D) pillared-layer 3d-4f heterometallic coordination polymers (HCPs) with three structural types. They are formulated as [Ln2Cu2(μ2-X)(hma)(ina)4(H2O)2]n·2nH2O [Ln = La, X = Cl (I-A), Ln = La, X = Br (I-B), Ln = La, X = I (I-C), Ln = Nd, X = Cl (I-D), Ln = Nd, X = Br (I-E)], [Ln3Cu4.5I3.5(μ3-OH)(hma)(ina)6(H2O)]n·nH2O [Ln = Pr (II-A), Nd(II-B)], and [LnCu0.5(hma)(ina)(H2O)]n·nH2O [Ln = La (III-A), Ce (III-B), Pr (III-C)]. All the HCPs are characterized by single-crystal X-ray diffractions. In type I structures, Ln-organic layers are pillared by halide-bridged dinuclear [Cu2(μ2-Cl)(ina)4] units through Ln–O bonds. In type II structures, Ln-organic layers are pillared by two different kinds of monovalent Cu-based building units, namely, halide-free [Cu(ina)2] and halide-containing [Cu8(μ3-I)6(μ4-I)(ina)10]n. In type III structures, undulate heterometallic C...
