Synthesis, crystal growth, crystal structure, optical, thermal, biological and NLO studies of heterocyclic compound N-(1,3-benzothiazol-2-yl)-2methoxybenzamide

Heterocyclic organic compound N-(1,3-benzothiazol-2-yl)-2-methoxybenzamide (N2BT2MBA) was synthesized by the process of benzoylation of 2-aminobenzothiazole using 2-methoxybenzoylchloride and structurally characterized. The compound N2BT2MBA molecular ion peak at 284.3 was confirmed by gas chromatographic mass spectrometry [GC-MS]. The single crystal X-ray diffraction (room temperature and liquid nitrogen temperature) study reveal that N2BT2MBA crystallized with methanol solvate exhibit a triclinic system with space group P-1. FT-IR spectra of N2BT2MBA molecule confirm the presence of carbonyl functional group vibration mode at 1654 cm(-1). The absorbance band of N2BT2MBA compound in UV-NIR region found at 305 nm and the optical band gap to be 3.67 eV. H-1 and C-13 NMR spectral analysis were used to predict the placement of protons and carbons in the N2BT2MBA molecule respectively. Thermal analysis of grown crystals N2BT2MBA were confirmed by TGA & DTA analysis and the crystal was found to be stable up to 160 degrees C. The antibacterial and antifungal activity of N2BT2MBA compound was tested using ciprofloxacin and amphotericin-B as a standard by zone of inhibition method. The results show that the compound active. The second harmonic generation (SHG) was confirmed by Kurtz-Perry powder technique for N2BT2MBA crystal with the SHG efficiency 3.5 times greater than that of potassium dihydrogen phosphate [KDP].
