Eight coordination with bis(bidentate) bridging ligands: zeolitic topology versus square grid networks.
نویسندگان
چکیده
The assembly of the asymmetric bis(bidentate) 2-pyrimidinecarboxylate ligand with Cd(II) produces a metal-organic framework with the RHO zeolitic topology, while 5-(2'-pyrimidyl)tetrazolate with Cd(II) leads to square grid networks.

New coordination polymer of [HgLCl2]n (1) with HgCl2 and Schiff base bidentate ligand (4-methoxyphenyl) pyridine-2yl methyleneamine (L) was prepared and structurally characterized. In the 1D network structure of 1, the mecury (II) ion adopts an HgN2Cl3 distorted square pyramid geometry. In this complex, one of the chlorine acts as bridging ligand connecting two adjacent mercury(II) ions while, ...

A series of six novel mononuclear, binuclear and linear one-dimensional (1D) compounds of copper(II) with chloranilic acid (3,6-dichloro-2,5-dihydroxybenzoquinone, H2CA) is prepared and a design strategy for the preparation of such complexes is discussed. Four described compounds are linear 1D coordination polymers [Cu(CA)]n, whereas another two involve a binuclear and a mononuclear, Cu2(CA)3 a...

A new 1D chained Ca(II) coordination polymer—namely, [CaL2(H2O)2]n (HL = 3,5-bis(4-pyridylmethoxy)benzoic acid)—was synthesized though the reaction of Ca(ClO4)2·4H2O, 3,5-bis(4-pyridylmethoxy)benzoic acid and NaOH in H2O/CH3CH2OH (v:v = 1:2) solution. Its structure was determined by elemental analysis, infrared spectrum, and single-crystal XRD. Structural analyses show that each Ca(II) ion is e...

The title dimeric complex, [Eu(2)(C(7)H(5)O(2))(6)(C(3)H(7)NO)(2)(H(2)O)(2)], is centrosymmetric, implying that pairs of equivalent Eu(3+) ions and ligands lie trans to each other and that the two Eu(3+) ions have exactly the same coordination environment. Each Eu(3+) ion is nine-coordinated by two bidentate benzoate ligands, two bridging tridentate chelating benzoate ligands, and one dimethylf...
