Sažetak
Recently, it has been shown that it is possible to direct the supramolecular assembly in the organic solid state by employing certain supramolecular synthons. However, it still remains to be determined if those strategies are viable in the metal-organic setting due to disruptive effect of the counter-ion present in those surrounding. One of the approaches to tackle this problem is to employ charge-balancing ligands to coordinate to the metal cation thus consequently minimizing their disruptive effect. In our previous work on β-diketonato complexes of CoII and NiII, we were aiming to connect the metal-containing building blocks via self-complementary hydrogen bond synthons (R22(6) motifs) formed between the oxime groups from neighbouring coordination units. We have shown that the supramolecular outcome is primarily influenced by the acceptor potential of the oxygen atom form β- diketonato ligands, and in all the cases the hexafluoroacetylacetonate ligands, the targeted synthon was obtained. We have also shown that the position of the oxime group on the pyridine ring, accompanied with the electron donating –CH3 groups in the vicinity of the oxime nitrogen atom, can improve the hydrogen bonding acceptor power of the nitrogen atom for the desired synthon to be formed.
