A new Ca(II) coordination polymer, [{CaL2·(H2O)2·2H2O}]n (1) (L = 2-[(E)-(2furoylhydrazono)methyl]benzenesulfonate), has been obtained by one-pot method, and characterized by elemental analysis, IR spectrum, and X-ray single-crystal diffraction. The results showed that the Ca(II) coordination crystallizes in the orthorhombic space group with P21212, a = 16.355(3) Å, b = 17.478(4) Å, c = 5.4549(...

In the title compound, catena-poly[bis[(2,2'-bipyridine-κ(2)N,N')(1,1,3,3-tetracyano-2-ethoxypropenido-κN)copper(II)]-μ4-hexanedioato-κ(6)O(1),O(1'):O(1):O(6),O(6'):O(6)], [Cu2(C9H5N4O)2(C6H8O4)(C10H8N2)2]n, the adipate (hexanedioate) dianion lies across a centre of inversion in the space group P1. The Cu(II) centre adopts a distorted form of axially elongated (4+2) coordination, and the Cu(II)...

A bis-catechol ligand connected through an imine bond is used to fabricate switchable coordination polymer particles with pH-tuned spin transition responses.

A photoluminescent three-dimensional coordination polymer containing two types of cavities is prepared by the covalent linkage of 2D bilayer motif with linear connecting ligand.
