A new tripodal complex [ZnL](ClO4)2 (C26H31Cl2N7O8Zn) was synthesized by Schiff base condensation of 2-aminoethyl-bi (3-aminopropyl)amine with 2-pyridinecarbaldehyde in the presence of Zn2+ and characterized by Xray diffraction and ES mass spectral analysis. It crystallized in the Monoclinic system, space group P21/c with a=1.088 5(4) nm, b=1.614 6(6) nm, c=1.783 0(5) nm,β=94.405(2)°. Z=4, R1=0.092 9, wR2=0.175 8. Zn atom rendered six-coordinate in a trigonal antiprism geometry. The complex was valued for its antimicrobial activity against bacterial strands using the agar diffusion method. It was found to be active against the four test bacterial organisms.
