Abstract
A novel molecular tetrameric zinc cluster with phosphate bridges has been synthesized by a hydrothermal\nmethod and characterized by X-ray diffraction. The structure is stabilized by neutral H<sub>3</sub>PO<sub>4</sub> and water molecules. Both\nphosphorus and water oxygen atoms play a central role as connecting agents in this planar, weblike array. Protruding\nphenanthroline ligands bonded to the zinc atoms are present both above and below the plane, constituting the main\ninteraction between neighboring planes, through π−π stacking. The distance between ring centroids varies between 3.489\nand 4.109 Å.
