The preparations are reported for a range of complexes of the ligand N,N′-p-phenylenedimethy]enebis(pyridin-4-one) (XBP) with the d-block ions Mn(II) to Zn(II) and also with Cd(II), Y(III), and the lanthanide ions. Relevant solid state EPR, electronic and far-IR spectra are reported and interpreted in terms of the metal ion coordination geometries and, where appropriate, the likely long-range polymeric structures of the compounds. The value of the zero-field splitting (zfs) parameter, D = 0.069 cm-1, obtained from the S = 1 type EPR spectrum of the compound {[Cu2(XBP) 3(NO3)2](NO3)2· 2H2O}n is compared with those of other compounds involving discrete Cu ... Cu dimer interaction. The results of luminescence measurements on the complexes of Sm(III), Eu(III), Tb(III), and Dy(III) are also given.
