Structural characterization of μ1,2- and μ1,3-bridged-squarato 1D metal(II) coordination polymers

A number of 1-D polymeric coordination complexes derived from different polypyridyl ligands and divalent metal ions (Cu, Mn, Zn and Cd) bridged by squarato ligand in cis- and trans-bonding modes were structurally characterized.127
