dysprosium(III) complexes while the neodymium(III) complexes have been subjected to detailed investigations with respect to the hypersensitive band profile and its oscillator strength’s dependence on temperature and pH. On the basis of IR and NMR spectral studies, Hapnh is believed to act as a neutral tridentate species in the adduct complexes and as a uninegative tridentate one in the neutral complexes. Electrical

Within the six compounds, three feature 2D metal–organic networks, two are 1D coordinationpolymers, and another one comprises discrete 0D dimeric units. The structures of the latter low dimensional compounds are extendable into 2D supramolecular networks. The topology of the coordination or supramolecular networks is primarily dictated by the geometry of the nicotinoylhydrazone used as a main building

layer in 1 and a 1-D zigzag coordination chain in 2. Both 1 and 2 are constructed from six-coordinate Mn(II) nodes that adopt distorted octahedral (MnN5O) environments; the adjacent nodes are driven by the μ-L1 and μ-N3 linkers in 1 or μ-HL2 linkers in 2 to form different metal–organic networks. Their topological classification was performed, disclosing the hcb and 2C1 topology in 1 and 2, respectively
