Experimental data were complemented by quantum mechanical calculations. XRD data show that the compound crystallizes in the triclinic system (P 1) via trans isomer (a ¼ 6.4267(4) Å, b ¼ 10.9259(12) Å, c ¼ 12.4628(9) Å and a ¼ 102.894(8) , b ¼ 102.535(6) , g ¼ 101.633(7) ). Anti-microbial screening results indicate that the compound shows promising activity. The theoretically predicted and experimentally obtained parameters reveal further insight into pyrazoline systemsenArticle
