Abstract
AbstractThe preparation, X-ray crystal structure, fourier transform infrared (FTIR) spectroscopy, and elemental analysis of three compounds based on diethylenetriamine and aromatic carboxylic acids are reported. XRD and FTIR analysis indicated that all these complexes are organic salt. The compound 1 crystallizes in the triclinic, space group P-1, with a = 8.5665(8) Å, b = 11.8387(9) Å, c = 12.4901(11) Å, α = 77.2580(10)°, β = 77.1820(10)°, γ = 78.290(2)°, V = 1,188.81(18) Å3, Z = 2. The compound 2 crystallizes in the triclinic, space group P-1, with a = 8.0040(7) Å, b = 9.4869(8) Å, c = 20.3491(18) Å, α = 84.6370(10)°, β = 87.032(2)°, γ = 78.9620(10)°, V = 1,509.0(2) Å3, Z = 2. The compound 3 crystallizes in the orthorhombic, space group Pbca, with a = 12.1232(11) Å, b = 13.5714(14) Å, c = 26.179(3) Å, α = 90°, β = 90°, γ = 90°, V = 4,307.3(7) Å3, Z = 8. The supramolecular architectures of 1–3 involve extensive hydrogen bonding including N–H···O, N–H···N, and O–H···O interactions as well as other non-covalent CH–O, CH2–O, O–π, NH3+–π, CH2–π, and π···π interactions, giving 3D framework structures.Graphical AbstractThe crystal structures of the diethylenetriamine salts with 3,5-dinitrobenzoic acid, 2-hydroxy-5-(phenyldiazenyl)benzoic acid, and 5-nitrosalicylic acid show extensive classical hydrogen bonding as well as other non-covalent CH–O, CH2–O, O–π, NH3+–π, CH2–π, and π···π interactions, giving three-dimensional networks.
