A Lamellar Zn-Based Coordination Polymer Showing Increasing Photoluminescence upon Dehydration.

ABSTRACT: The present study reports on a 2D lamellar coordination polymer (CP) of {[Zn(µ₃-pmdc)(H₂O)]·H₂O}_n formula (pmdc = pyrimidine-4,6-dicarboxylate). This CP is synthesized under an appropriate acid-base reaction between the gently mortared reagents in the solid state through a solvent-free procedure that avoids the presence of concomitant byproducts. The X-ray crystal structure reveals the occurrence of Zn₂ entities connected through carboxylate groups of pmdc, which behave as triconnected nodes, giving rise to six-membered ring-based layers that are piled up through hydrogen bonding interactions. In addition to a routine physico-chemical characterization, the thermal evolution of the compound has been studied by combining thermogravimetri
