The Schiff base organotin(IV) complex {[4-Et₂NC₆H₃(O)C=NC₆H₃(O)-5-NO₂](n-Bu₂Sn)}₂ has been synthesized via the reaction between 4-(diethylamino) salicylaldehyde-2-amino-4-nitrophenol Schiff base (H₂L) and dibutyltin oxide. Complex C1 has been characterized by IR, ¹H NMR, ¹³C NMR spectra, and elemental analysis, and its crystal structure was determined by X-ray diffraction. It crystallizes in the monoclinic system, space group P2₁/n with a=15.6559(8), b=9.1657(5), c=18.8351(10) Å, β=107.3440(10)°, Z=4, V=2579.9(2) Å³, Dc=1.442 Mg·m^-3, μ(MoKα)=1.025 mm^-1, F(000)=1152, R=0.0250 and wR=0.0633. The central Sn atom is coordinated in a hexadentate manner to assume a distorted octahedral configuration. Complex C1 was studied by TGA analysis in air atmosphere. The interaction between complex C1 and the herring sperm DNA was realized through the intercalation of the complex based on the studies by EB fluorescent probe.
