A novel supramolecular complex (C10H10N2) Co (SCN) 4 was synthesized at room temperature and characterized by elemental analysis, IR and single crystal X-ray diffraction. The title compound belongs to the orthorhombic, P 21 21 2 space group with a = 1.283 32 (11) nm, b = 1.297 53 (12) nm and c = 0.544 12 (5) nm with V = 0.906 04 , Z = 2. In the compounds, each Co2 + ion forms a distorted tetrahedral geometry with 4 N atoms of 4 SCN-, the two nitrogen atoms of the 4,4’-dipyridyl are di-protonated and interacted with the S atoms of SCN- Form N-H ... S hydrogen bonds, forming one-dimensional hydrogen bonding supramolecular chains. The thermal stability of the compound was investigated by thermogravimetric analysis.
