Abstract
The structures of coordination compound of poly(ethylene-co-methacrylic acid-co-methacrylato) with Co(II) and its adducts of 1,3-bis(aminomethyl)cyclohexane (BAC) were studied from visible spectral and ESR measurements in the temperature range from room temperature to 130°C. The Co(II) complexes were in an octahedral coordination at room temperature, but transformed into a tetrahedral coordination with increasing temperature. The Co(II) complexes coordinated with BAC were in the tetrahderal one, regardless of temperature. The transformation from octahedral to tetrahedral structure was closely associated with the order-disorder transition of ionic clusters.
