A new acesulfame derivative compound, trans-diaquabis(trans-4-aminoantipyrine)cobalt(II) acesulfamate that formulated as (C30H38CoN8O12S2) was synthesized and characterized by X-ray diffraction method, FT-IR, UV-Vis techniques and Thermal analysis. The compound crystallizes in the orthorhombic space group Pbcn with parameters a = 28.0156 (10) angstrom, b = 9.4273 (4) angstrom, c = 13.7777 (5) angstrom, alpha = beta = gamma = 90 degrees, Z = 4. Theoretical calculations have been carried out by using Density Functional Theory (DFT) method in the ground state. With a successful optimization, Mulliken population method, molecular electrostatic potential (MEP) and frontier molecular orbitals were calculated. In addition, the thermal behavior of the complex was investigated. Hirshfeld surface analyses (d(norm) surfaces and two-dimensional fingerprint plots) which reveal the nature of intermolecular interactions for the title compound were performed and discussed. The Hirshfeld surface analysis of the crystal structure specifies that the most important contributions for the crystal packing are from O center dot center dot center dot H/H center dot center dot center dot O (37.1%), H center dot center dot center dot H (33.5%) and C center dot center dot center dot H/H center dot center dot center dot C (16.5%) interactions.
