A new organic–inorganic hybrid material of formula (C10H15N2)7 Sb2Cl10 Sb2Cl9 (SbCl5)2 SbCl4 2Cl·7H2O was synthesized and characterized by an X-ray diffraction analysis. It crystallizes in the triclinic system with the P(Formula presented.) space group and the following unit cell parameters a = 11.8127(3) Å, b = 15.7557(4) Å, c = 35.4511(8) Å, α = 89.409(1)°, β = 84.04(1)°, γ = 71.116(1)°, Z = 2 and V = 6207.3(3) Å3. The examination of the structure shows that the two dimensional frameworks are produced by O–H Cl, N–H⋯Cl and N–H⋯O hydrogen bonding. In addition, the most important features of crystal packing and intermolecular interactions in the title complex were quantified via Hirshfeld surface analysis. Differential scanning calorimetry has revealed a dehydration phenomenon at around 348 K. The investigation of the antioxidant activity of the title compound was carried out using the 2,2-diphenyl-1-picrylhydrazyl and ferrous iron chelating methods.
