Beta-sheet recognition in the non-interpenetrated and interpenetrated two-dimensional coordination networks containing cavities.

چکیده
Two types of secondary building units of CuI (Cu2I2 and Cu4I4) were shown to generate 2D-coordination networks of (4,4)-topology (non-interpenetrated and interpenetrated) with exo-bidentate ligands that contain diamide as spacer.

Solid state interconversion of cages and coordination networks via conformational change of a semi-rigid ligand.
The reaction of silver(i) perchlorate with the semi-rigid ligand 1,4-bis((3,5-dimethylisoxazol-4-yl)methyl)benzene (bisox) in methanol gives a triply-interpenetrated sheet structure, but a structure containing both interpenetrated sheets and Ag(2)(bisox)(3) cages is formed on recrystallisation from acetonitrile-diethyl ether. Rearrangement of the cages into sheets occurs on heating under vacuum...
متن کاملLone pair-π interaction-induced generation of non-interpenetrated and photochromic cuboid 3-D naphthalene diimide coordination networks.
Interpenetration is an intrinsic behaviour for the porous coordination networks. To prevent the interpenetration, a common strategy is the imposition of geometric or steric restrictions by incorporating bulky moieties into organic tectons. So far, most of the available incorporations have been achieved through a covalent connection, while few involved in the non-covalent weak interactions. In t...
متن کاملEnantiomeric two-fold interpenetrated 3D zinc(ii) coordination networks as a catalytic platform: significant difference between water within the cage and trace water in transesterification.
Self-assembly of Zn(ClO4)2 with 1,1,2,2-tetramethyl-1,2-di(pyridin-3-yl)disilane (L) as a bidentate N-donor gives rise to 3D coordination networks, [Zn(μ-OH)(L)]3(ClO4)3·5H2O (1·5H2O), of unique, 103-a srs net topology. An important feature is that two enantiomeric 3D frameworks, 41- and 43-[Zn(μ-OH)(L)]3(ClO4)3·5H2O, are interpenetrated to form a racemic two-fold 3D network with cages occupied...
متن کاملA 2D cobalt based coordination polymer constructed from benzimidazole and acetate ion exhibiting spin-canted antiferromagnetism.
A coordination polymer, [Co(II)(bIM)(acetate)] (bIM = benzimidazole) was synthesized using a solvothermal method; the complex has a two dimensional non-interpenetrated network structure and exhibits a spin-canted antiferromagnetic behaviour at low temperature and a high coercive field.

Four new coordination compounds, namely {[Cd(3)(L)(2)(mu(3)-OH)(2)(H(2)O)] x H(2)O}(n) (1), {Ni(L)(bipy)}(n) (2), {Cu(3)(L)(2)(bipy)(mu(2)-OH)(2)(DMF)(2)}(n) (3), and {Co(2)L(2)(H(2)L)(H(2)O)}(n) (4), have been synthesized by the solvothermal reaction of 4,4'-(hexafluoroisopropylidene)bis(benzoic acid) (H(2)L) with different transition metal ions in the presence of co-ligand 4,4'-bipyridine (bi...
