Analysis of supramolecular interactions directing crystal packing of a trans,trans,trans-[diaquabis(4-quinolin-3-yl)-4H-1,2,4-triazole)bis(tricyanomethanide)iron(II)] complex: A combination of XRD, MEP, NBO, QTAIM, and NCI analyses

•A new centrosymmetric iron(II) complex is prepared under solvothermal conditions.•Supramolecular interactions are analyzed using a variety of computational methods.•Complex creates a 3D network due to ability of tcm in forming diverse interactions.•This work provides a better understanding of interactions in the solid state.
