₂, has been prepared by slow evaporation from an aqueous solution. It was investigated by means of single-crystal X-ray diffraction, infrared spectroscopy and thermal analysis. The title compound crystallise in orthorhombic space group Pbcn, with unit cell parameters at 298(1) K of a = 9.5538(19) Å, b = 9.1466(18) Å, c = 21.9222(4) Å, V = 1915.7(7) Å

₂ tetrahedra establishing eight-membered ring cavities. This mixed-polyhedral motive is decorated with the ortho-phenylenediamine ligands towards the inter-layer region thus forming a cationic organic-inorganic hybrid layer charge compensated by the chlorine anions. Infrared spectroscopy revealed absorption bands corresponding to the ortho-phenylenediamine molecule and the hypophosphite anion. The compound was proven to be stable up to 474 K under N
