The in fluence of PABA(p-aminobenzoicacid) and HEEDTA (N-(2-hydro xyethyl) ethylenediamine-N, N, Ntriacetic acid) on Strontionite crystals via simp le CO 2 d iffusion route is described. The results showed that the experimental parameters have great influence on the shape evolution of products. The presence of templating species and varied pH are the key prima ry conditions for the g rowth morphology. Spike like crystals self assembled in the form o f flo wer like and cauliflower shaped cluster

... with high crystallin ity were identified. The crystals undergo an interesting morphology changes and have been characterized by X-ray d iffraction (XRD), Scanning Electron M icroscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) techniques.
