Abstract
SE DESCRIBE UN COMPUESTO METALICO TETRAVALENTE DE DIFOSFATO-FOSFITO DEFINIDO POR LA FORMULA GENERAL SIGUIENTE: DONDE: M ES UN METAL TETRAVALENTE; X VARIA DESDE 0.5 A 0.66; R ES UN RADICAL ORGANICO DE TIPO AROMATICO BIVALENTE, GRUPOS LATERALES TRANSPORTADORES QUE AUMENTAN SU IMPEDIMENTO ESTERICO. EL COMPUESTO SE PRESENTA EN FORMA DE UN SOLIDO CRISTALINO CON UNA ESTRUCTURA DE CAPA DE TIPO (ALFA) CON LOS GRUPOS DIFOSFORICOS POSICIONADOS DE FORMA QUE PUEDAN JUNTAR DICHAS CAPAS CONJUNTAMENTE MEDIANTE UN AGLUTINADOR COVALENTE COMPUESTOS SOSTENIDOS POR COLUMNAS). TIENE UNA SUPERFICIE B.E.T. DESDE 300 HASTA 500 M (AL CUADRADO) /G QUE DEPENDEN DE LA NATURALEZA DE R EN LA FORMULA (I), Y DE UNA POROSIDAD EN EL RADIO DEL MICROPORO EN UNA PROPORCION MENOR QUE 20 ANGSTROM, DICHOS MICROPOROS CONTRIBUYEN A LA EXTENSION DE MAS DEL 95% DEL AREA TOTAL PARA LA MAYORIA DE LOS MATERIALES CRISTALINOS.
