UV-vis spectra, fluorescence spectra and X-ray crystallography. The heterometallic complexes were acquired by the reaction of H4L with 2 equiv. of Ni(OAc)2·4H2O and 1 equiv. of M(OAc)2 (M = Ca, Sr and Ba). The crystal structures of complexes 1–3 have been determined by single-crystal X-ray diffractions. Owing to the different nature of the N2O2 and O6 sites of the ligand H4L, the introduction of two different
