Photochemical single-crystal to single-crystal transformation of one 1D polymer [Cd(bpe)(CBA)(2)](n) afforded a new 1D polymer [Cd(rctt-tpcb)(0.5)(CBA)(2)](n) which underwent hydrothermal reaction in strong acidic solution to form a 3D coordination polymer {[Cd(rtct-tpcb)Cl(2)]·2H(2)O}(n).
The anisotropy of polarization in a 1D copper(II)-based coordination polymer was investigated experimentally and theoretically for the first time, revealing that the origin of the ferroelectricity and its anisotropic nature are closely related to the coordination geometry of the metal ion and the packing mode of the coordination polymer.
Nano-structured copper oxides were successfully prepared through direct calcination of 1D ladderlike metal-organic framework [Cu2(btec)(2,2'-bipy)2]∞, (btec = 1,2,4,5-benzenetetracarboxylate and 2,2'-bipy = 2,2'-bipyridine) and porous coordination polymer [Cu(BDC)(bipy)](BDCH2), (BDC = 1,4-benzenedicarboxylate; bipy = 4,4'-bipyridine). The nano-structure of the as-synthesized samples are charac...
A relatively inflexible 1D coordination polymer is induced to adopt either planar or quintuple helical supramolecular isomers according to the hydrogen bonding demands of the counter anions.
A discrete dinuclear Ag(I) complex undergoes a single-crystal-to-single-crystal transformation to generate a 1D coordination polymer with a polycyclobutane backbone.
Four novel ZnII coordination polymers, [(ZnCl₂)₂(L)₂]n (1), [(ZnBr₂)₂(L)₂]n (2), and [(ZnI₂)₂(L)₂]n (3) and {[Zn(SCN)₂]1.5(L)₃}n (4), have been synthesized based on 4'-ferrocenyl-3,2':6',3''-terpyridine with ZnII ions and different coordination anions under similar ambient conditions. Their structures have been confirmed using single crystal X-ray diffraction analysis, showing that complexes 1-...
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 this research, 1D four-coordinate copper(I) coordination Polymer [Cu(Clba2-1,2-pn)(NCS)]n (1) with thiocyanate anion as bridging ligand, where Clba2-1,2-pn = N,Nʹ-bis(2,4-chlorobenzylidene)propane-1,2-diamine), was synthesized by slow evaporation of solvent at room temperature and characterized by elemental analysis (CHN) and single-cryst...
Thermal annealing of a discrete complex with terminal SeCN anions and monodentate coligands enforces the formation of a 1D cobalt selenocyanato coordination polymer that shows slow relaxation of the magnetization. Therefore, this approach offers a rational route to 1D materials that might show single chain magnetic behaviour.
