Crystal and Molecular Structures of Three Salts from Diethylenetriamine, 3,5-Dinitrobenzoic Acid, 2-Hydroxy-5-(Phenyldiazenyl)Benzoic Acid, and 5-Nitrosalicylic Acid

摘要

The 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) , b = 11.8387(9) , c = 12.4901(11) , alpha = 77.2580(10)A degrees, beta A = 77.1820(10)A degrees, gamma A = 78.290(2)A degrees, V = 1,188.81(18) (3), Z = 2. The compound 2 crystallizes in the triclinic, space group P-1, with a = 8.0040(7) , b = 9.4869(8) , c = 20.3491(18) , alpha = 84.6370(10)A degrees, beta A = 87.032(2)A degrees, gamma A = 78.9620(10)A degrees, V = 1,509.0(2) (3), Z = 2. The compound 3 crystallizes in the orthorhombic, space group Pbca, with a = 12.1232(11) , b = 13.5714(14) , c = 26.179(3) , alpha = 90A degrees, beta A = 90A degrees, gamma A = 90A degrees, V = 4,307.3(7) (3), Z = 8. The supramolecular architectures of 1-3 involve extensive hydrogen bonding including N-H center dot center dot center dot O, N-H center dot center dot center dot N, and O-H center dot center dot center dot O interactions as well as other non-covalent CH-O, CH2-O, O-pi, NH3 (+)-pi, CH2-pi, and pi center dot center dot center dot pi interactions, giving 3D framework structures.
