Four two-dimensional frameworks {[Nd(dpa)(C2O4)(H2O)]·(H2O)}n (1), {[Ln2(dpa)2(C2O4)2(H2O)2]·(H2O)}n (Ln = Eu (2), Gd (3), Tb (4)) (dpa = 2,2′-(2-methylbenzimidazolium-1,3-diyl)diacetate, C2O42− =Expand
Synthesis and structures of helical and meso-helical coordination polymers directed by the conformation restriction of flexible/angular pyridine-containing ligands
Six coordination polymers, {[Ni(L1)2(H2O)2]·(H2O)4}n (1), {[Co(L1)2(H2O)2]·(H2O)4}n (2), [Co(L2)2]n (3), {[Hg3(L3)2Cl6]·(CH3OH)4·(H2O)2}n (4), {[Hg3(L3)2I6]·(H2O)3}n (5) andExpand
{μ-trans-N,N′-Bis[(diphenylphosphanyl)methyl]benzene-1,4-diamine-κ2 P:P′}bis{(acetonitrile-κN)[dipyrido[3,2-a:2′,3′-c]phenazine-κ2 N 4,N 5]copper(I)} bis(tetrafluoridoborate)
In the centrosymmetric dinuclear title compound, the CuI centre is coordinated by two N atoms from a dipyridophenazine ligand, one P atom from an N,N′-bis[(diphenylphosphanyl)methyl]benzene-1,4-diamine (bpbda) ligand and an acetonitrile molecule in a distorted tetrahedral geometry. Expand
Tetraaquabis(2-methylbenzimidazolium-1,3-diacetato-κO)zinc(II) tetrahydrate
In the crystal structure, strong intra- and intermolecular O—H⋯O hydrogen bonds link the molecules into a three-dimensional network and results in the formation of a non-planar six-membered ring. Expand
A double-layered zinc(II) coordination polymer with the ligand 3,5-bis(carboxylatomethoxy)benzoate.
This submission shows a versatile polycarboxylate ligand with rigid and flexible functional groups, the co-operation and complementarity of which would meet the coordination requirements of a variety of topological structures. Expand
Tetraaquabis(2-methylbenzimidazolium-1,3-diacetato-[kappa]O)zinc(II) tetrahydrate
The asymmetric unit of the title compound, [Zn(C12H11N2O4)2(H2O)4] 4H2O, contains one-half of the complex molecule and two uncoordinated water molecules. The four water O atoms in the equatorialExpand
A coordination polymer of CdCl2 with the novel zwitterionic dicarboxylate ligand 2,2'-(2-methylbenzimidazolium-1,3-diyl)diacetate (pda).
This study synthesises a paddlewheel-based polymer constructed with a novel multifunctional zwitterionic dicarboxylate ligand which is consolidated by pi-pi interactions between benzene rings of benzimidazole groups. Expand
