Coexistence of planar tetramer and cyclic octamer water clusters in a polymer: Synthesis, DFT study and magnetism

A new complex 1 with flexible and rigid coligands shows a 1D chain. Two different (H2O)8 and (H2O)4 water clusters are observed, in which are further extend into a big (H2O)10 cluster.In addition, the magnetic behavior of 1 shows antiferromagnetic exchange within Co magnetic centers.
