Polymorphism and symmetry non-equivalence in (3-carboxymethoxy-naphthalen-2-yloxy) acetic acid

Separation or combination of non-covalently linked partners provides polymorphs of N-(aryl)-2-(propan-2-ylidene)hydrazine carbothioamides

Polymorphs of N-(2-methoxyphenyl)-2-(propan-2ylidene)hydrazine carbothioamide and N-(4-nitrophenyl)-2-(propan-2-ylidene)hydrazine carbothioamide differing in homomeric assemblies are described.

Packing polymorphism in 3-amino-2-pyrazinecarboxylate based tin(ii) complexes and their catalytic activity towards cyanosilylation of aldehydes

3-Amino-2-pyrazinecarboxylic acid is used to synthesize two new mononuclear interconvertible packing polymorphs of tin(ii) which act as heterogeneous catalysts for the cyanosilylation of aldehydes with trimethylsilyl cyanide.

Recent advances on supramolecular isomerism in metal organic frameworks

This review highlights selected examples of supramolecular isomerism in the area of metal organic frameworks and major factors of their formation are also discussed.

Zinc amidoisophthalate complexes and their catalytic application in the diastereoselective Henry reaction

5-Propionamidoisophthalic acid and 5-benzamidoisophthalic acid are used to synthesize new zinc(ii) complexes which act as heterogeneous catalysts for the diastereoselective nitroaldol (Henry) reaction.

Coordination polymers of zinc with 2,2'-(2,3-bis-phenylsulfanylnaphthalene-1,4-yloxy)diacetic acid

Coordination polymers of zinc with 2,2'-(2,3-bis-phenylsulfanylnaphthalene-1,4-yloxy)diacetate with different ancillary ligands such as pyridine, dimethylformamide and water are prepared and characterized. The dimensionality of zinc derived coordination polymers from (4-carboxymethoxy-2, 3-bis-phenylsulfanyl naphthalene-1-yloxy)-diacetate can be changed by ancillary ligands. In the case of pyridine as ancillary ligand it forms a one-dimensional coordination polymer, whereas in the case of dimethylformamide it is a two-dimensional polymer.
