Abstract:
Under hydro(solvo)thermal conditions, two 4-(4-carboxyphenoxy)phthalate-based three-dimensional (3-D) coordination polymers: [Cd3(cpph)2(bpa)2(H2O)]·0.5H2O (cpph = 4-(4-carboxyphenoxy)phthalate, bpa = 1,2-bis(4-pyridyl)ethane) 1, and [H2(bpp)][Mn2(cpph)2(H2O)2] (bpp = 1,2-bis(4-piperidyl)propane) 2 were isolated. In both compounds, the cpph molecules extend the metal ions into a 3-D network: a (4,6)-connected net for 1 and a simple 6-connected net with a pcu topology for 2. The introduced bpa or bpp molecule stabilizes the 3-D metal-cpph architecture in the form of linker or guest molecule. The sensing ability of 1 was investigated, revealing that it can be used as a fluorescence probe to sense nitrobenzene at ppm concentrations.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly,...
