Abstract:
A rare example of coordination at the amino group of NH2 pym (2-aminopyrimidine) relevant to N-H activation is described that leads to a novel Ag(I) -imide 3D metal-organic framework (MOF). The coordination of Ag(I) to NH2 pym produced an electron-withdrawing effect and thus increased its acidity, which facilitated the N-H activation and the subsequent formation of the Ag-imide bond. A cooperative metalation/deprotonation process for the N-H activation of NH2 pym is suggested. Interestingly, photoluminescence of 1 is switched on at the low temperature of 77 K.

Imines are formed under mildly acidic conditions. A pH of 4.5 is ideal for the reaction.
If the pH is low or the solution is too acidic, the reaction slows down in the...
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,...
