Abstract
The polymeric complex [{Cu3(guop)3(OH2)8·5H2O}n](guop = guanosine monophosphate) has been studied by i.r., e.s.r., and electronic spectroscopy and by magnetic-susceptibility measurements. The PO4 bonding to CuII in this complex does not differ much from that of other oxygen donors, and there are two sets of magnetically coupled copper(II) ions with –2J values of 130 and 15 cm–1, respectively. Corresponding coupling paths are proposed. A value of the zero-field splitting, |D|= 0.15 cm–1, has been obtained for the strongly coupled species.Keywords
