tris(p-tetrazolylphenyl)amine (H3TTPA) ligand and the new Mn2+ frameworks [Mn3(TTPA)2(MeOH)6]n (1) and [Mn3(TTPA)2(DMF)6]n (2). Oxidation of H3TTPA generated the triarylamine radical which was found to be delocalised throughout the ligand backbone. Solid state Vis/NIR and EPR spectroelectrochemical experiments on the frameworks were used to probe the optical properties of the accessible redox states

A series of Cu(II) complexes showed unprecedented reversible cascades of single-crystal-to-single-crystal (SCSC) transformations, and more interestingly, very rapid crystal dynamic processes were observed in this system via the substitution of coordinating components without loss of single crystallinity.

Three new Mn(II) and Cd(II) coordination polymers with kgd network topology, namely, [Mn-3(T-4)(2)(DEF)(6)] center dot 2H(2)O (1), [Mn-3(T-4)(2)(DMSO)(2)(CH3OH)(4)] center dot 2CH(3)OH center dot 3H(2)O (2) and [Cd-3(T-4)(2)(DMF)(6)] center dot 5CH(3)OH center dot 3DMF center dot H2O (3), have been prepared by reactions of tris[4-(1H-tetrazol-5-yl)phenyl]amine (H3T4) with corresponding metal salt and characterized by single crystal and powder X-ray diffractions, IR and thermogravimetric analyses. In compounds 1 and 3, the layers adopt center to center stacking, while there is a slight shifting between the adjacent layers in compound 2. Complexes 1 and 2 exhibit overall weak antiferromagnetic coupling between the neighboring Mn(II) atoms, and compound 3 shows luminescent property in the solid state at room temperature.
