Synthesis and Structure of Na2[(HO3PCH2)3NH]1.5H2O: The First Alkaline Triphosphonate

Two New Organo-Inorganic Hybrid Compounds: Nitrilophosphonates of Aluminum and Copper

“…A possible N}H stretching vibration (see discussion below) should be located in this range. The broad bands centered at 2650 and 2370 cm\ are related to PO}H vibrations and are always present in the IR spectra of phosphonates containing hydrogen phosphonate groups (7,8). The broad band centered at 1610 cm\ is due to the bending vibration of the water molecule.…”

Crystal growth and characterization of zinc–(amino-tris-(methylenephosphonate)) organic–inorganic hybrid networks and their inhibiting effect on metallic corrosion

“…Structurally characterized metal-AMP materials reported in the literature include Mn-AMP (that is isostructural to Zn-AMP reported herein) [15,16], Ca-AMP, [4a,17], Pb-AMP [18], Na-AMP [19], and Al-AMP [20].…”

Adsorption of Cd2+ and Cu2+ ions from aqueous solutions by a cross-linked polysulfonate–carboxylate resin

“…The first slow weight loss of 3.0% resulted from the release of water trapped in the cross-linked polymer. The first sharp loss of 22.4% resulted from the release of SO 2 , the second loss of 28.9% and the third loss of 7.7% were associated with the respective decarboxylation of the carboxylates and the degradation of the nitrogenated organic fraction (Martinez-tapia et al, 2000). At 800°C, the residual mass was found to be 38%.…”
