Data on in-vitro antibacterial activity and third order NLO property of 2-aminopyridine copper sulphate (2APCS)

•2APCS crystal was harvested using slow evaporation process in ambient temperature.•In linear optical study UV cut off wavelength 237 nm and 97% transparency in the entire visible regions are recorded.•In photoluminescence, emission of green laser attests the optical application of the 2APCS crystal.•The mechanical coefficient value n = 4.77 calculated using vickers microhardness test, confirms the 2APCS fit in to soft category.•THG parameters were calculated for 2APCS using Z- scan technique.•In antimicrobial activity, compound 2APCS was most effective retarding microbial growth of the bacteria enterococcus faecalis (MTCC 439) followed by other bacteria Escherichia coli (MTCC 443) and staphylococcusaureus (MTCC 96), but compared to the standard streptomycin our compound was not much effective. Solution growth technique was used to harvest nonlinear optical 2-aminopyridine copper sulphate (2APCS) crystal at room temperature. Crystallinity in 2APCS crystal was confirmed by powder XRD. Single XRD study reveals 2APCS crystallizes in triclinic system. Band assignments of synthesized compound were identified using FT-IR study. Linear optical study shows lower cut-off wavelength 237 nm for 2APCS. Mechanical behavior study of 2APCS crystal posses soft nature of the sample. Third harmonic generation (THG) study was analyzed using Z-scan Technique for 2-aminopyridine copper sulphate (2APCS) crystal. In-vitro antibacterial test was carriedout for the 2APCS sample using test pathogenic bacteria, Escherichia coli (MTCC 443), S.aureus (MTCC 96) and E.faecalis (MTCC 439) were tested to find the antimicrobial activity.
