A new zinc phosphonocarboxylate Na[Zn(O 3 PC 2 H 4 CO 2 )]·H 2 O ( 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(O 3 PC 2 H 4 NH 2 ) and Zn(O 3 PC 2 H 4 CO 2 H)·1.5H 2 O. TGA shows the trapped water molecules in 1 can be thermally removed without damage to the framework. Furthermore, dehydrated 1 is stable up to 340 °C. (© Wiley‐VCH Verlag GmbH & Co.
