Abstract
dc.description.abstract
The synthesis of a new mixed metal-organic framework ( M ' MOF) has been accomplished by the metalloligand approach. [ NaCu( 2,4- HPdc)( 2,4- Pdc)] ( 2,4- H2Pdc = pyridine2,4- dicarboxylic acid) has been obtained from the hydrothermal reaction of the metalloligand [ Cu( 2,4- HPdc) 2( H2O) 2] NaOH, and a transition metal salt. [ NaCu( 2,4- HPdc)( 2,4- Pdc)] is isostructural to [ CuMn( 2,4- Pdc) 2] and crystallizes in the triclinic space group P1. The 3D structure is built up from [ Cu( 2,4- HPdc) 2( H2O) 2] metalloligands and NaO6] octahedra in a pcu alpha- Po- like uninodal six- connected net. The compound is stable to 290 degrees C, and its crystal structure undergoes a 3% volume expansion between room temperature and thermal decomposition. The unsaturated CuII centers at the surface act as a heterogeneous Lewis acid catalyst for the cyanosilylation of aldehydes and Knoevenagel C- C bond- forming reactions. The catalytic activity has been compared with those of other copper( II) porous metalorganic frameworks such as HKUST- 1 and MOF- 74.
