Expanding and quantifying the crystal chemistry of the flexible ligand 15aneN5

Tetraazamacrocycles have been very extensively exploited as transition metal ligands for a variety of purposes, including catalysis, medical imaging, pharmaceuticals, etc. However, the pentaazamacrocycles are much less commonly used for...

A series of POM compounds constructed by a flexible ligand containing three coordination groups: electrocatalytic, photocatalytic reduction and amperometric detection of Cr(VI)

Four polyoxometalate-based compounds were synthesized by hydrothermal method, namely [Ni2(HPtpi)(H2O)7.5Mo0.17(TeMo6O24)]·2.5H2O (1)，[Co(HPtpi)2(H2Ptpi)2(GeMo12O40)2]·4H2O (2) and {[M(Ptpi)(H2Ptpi)(H2O)][(γ-Mo8O26)0.5(α-Mo8O26)0.5]}·4H2O (M = Co in 3; Ni in 4) (Ptpi = 1-[2-(3-Pyridin-4-yl-[1,2,4]triazol-4-yl)-propyl]-imidazol). Compound 1 exhibits a 3D...
