A new zinc phosphonocarboxylate Na[Zn(O3PC2H4CO2)](H2O)-H-. (1) has been hydrothermally synthesized by base-catalyzed hydrolysis of trimethyl 3-phosphonopropionate. An X-ray crystallographic study revealed that 1 consists of parallel stacked inorganic hexagonal sheets which are connected by organic -C-C-C-O- pillars forming a three-dimensional framework with the same topology as ABW-type zeolites. The accessible channel of 1 consisting of 22 atoms is larger than those of ABW-type zeolites and the metal phosphonates Zn(O3PC2H4NH2) and Zn(O3PC2H4CO2H)(.)1.5H(2)O. TGA shows the trapped water molecules in I can be thermally removed without damage to the framework. Furthermore, dehydrated 1 is stable up to 340 degreesC.
