Two-dimensional Mn(II) and Cd(II) networks with tetrazole-containing ligand and their properties

Abstract Three new Mn(II) and Cd(II) coordination polymers with kgd network topology, namely, [Mn 3 (T 4 ) 2 (DEF) 6 ] · 2H 2 O ( 1 ), [Mn 3 (T 4 ) 2 (DMSO) 2 (CH 3 OH) 4 ] · 2CH 3 OH · 3H 2 O ( 2 ) and [Cd 3 (T 4 ) 2 (DMF) 6 ] · 5CH 3 OH · 3DMF · H 2 O ( 3 ), have been prepared by reactions of tris[4-(1H-tetrazol-5-yl)phenyl]amine (H 3 T 4 ) 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.
