Powder XRD and TEM image analyses suggest a new disordered microporous structure with pores of dimension ca. 0.54 nm, and C-13 and Si-29 MAS NMR and spectroscopic results indicate the presence of bridging organic bis(propyliminomethyl) benzene moiety in this framework. TPD-NH3 results suggested that nearly 5 times as much bis(propyliminomethyl) benzene moiety is located inside the micropore walls (matrix) than in the surface of the pores. LHMM-2 shows very high adsorption capacity for metal cations like Fe3+, Cu2+ and Zn2+.</p>1 aPaul, Manidipa1 aPal, Nabanita1 aRajamohanan, P., R.1 aRana, Bharat, S.1 aSinha, Anil, K.1 aBhaumik, Asim  uhttps://library.ncl.res.in/content/new-organic-inorganic-hybrid-microporous-organosilica-having-high-metal-ion-adsorption-0
