Two new compounds, [Ni2（L1）（Py）6]Py·CH3OH（1） and [Ni3（LZ）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 diffraetion（XRD）. Compound 1 possesses a binuclear cluster, in which the bisalicylbisthi- ocarbamide 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--…S weak interactions further link these molecules to form interesting supramolecular networks.
