Considerable current interest is focused on the design and preparation of molecular-based 
magnetic materials because of their great value in investigation of magnetostructural 
relationships and some fundamentally magnetic behaviors. Herein, the results of variable-
temperature  magnetic susceptibility measurements of novel series of structurally characterized 
5-R-tetrazolato- (RCN4, where R = H, Ph, 4-Py [4-pyridyl]) and 5-R'-1(2)-methyltetrzole-
bridged (R'CN4-1(2)-Me, where R' = NH2, Me) 3d metal complexes were performed. It was 
found, that in copper(II) complexes, namely [Cu(HCN4)2(en)]n, [CuZn(HCN4)4(en)2]n, 
Cu2(PhCN4)4(en)2 2DMSO, {[Cu(4-PyCN4)2(DMSO)2] 4DMSO}n, [Cu(CH3CN4-1-Me)Cl2]n and 
[Cu(NH2CN4-2-Me)2Cl2]n, the coupling between paramagnetic centers through the bridging 
tetrazole containing ligands is always antiferromagnetic, but the exchange coupling strength is 
different due to varied linking modes of tetrazole containing ligands. Replacement of Cu(II) 
centers in complex with composition of [M(CH3CN4-1-Me)Cl2]n by anisotropic Co(II) ions 
yields the ferromagnetic ordering of the system [Co(MeCN4-1-Me)Cl2]n via chlorido and 
tetrazole bridges.
