Syntheses and supramolecular structures of two nickel(II) compounds based on two thiosemicarbazone ligands
Two new compounds, [Ni2(L1)(Py)6]Py·CH3OH(1) and [Ni3(L2)2(Py)4]·2DMF(2)(H4L1=N,N′-bisalicyl-bisthiocarbamide; H3L2=3-hydroxyl-2-naphthalene thiosemicarbazide; Py=pyridine; DMF=dimethyl fumarate), based upon two thiosemicarbazone ligands have been obtained and characterized by elemental analysis, Fourier transform infrared(FTIR) and X-ray diffraction(XRD). Compound 1 possesses a binuclear cluster, in which the bisalicylbisthiocarbamide acts as a hexadentate bridge. Compound 2 exhibits a linear trinuclear cluster with the triply-deprotonated ligand acting as pentadentate bridge. C—H…O, C—H…π and C—H…S weak interactions further link these molecules to form interesting supramolecular networks.
