Abstract The crystal synthesis and structure of a new organic monohydrogenmophosphate (3,4‐Cl 2 ‐CH 2 C 6 H 3 NH 3 ) 2 HPO 4 ·2H 2 O are reported. This compound crystallizes in the monoclinic P2 1 /n with a = 9.081(7) Å, b = 6.501(5) Å, c = 35.423(12) Å, β = 91.09(5)°, V = 2090.9(2) Å 3 , and Z = 4. Crystal structure was solved and refined to R = 0.042, using 2543 independent reflections. It can be described by inorganic layers, including the HPO 4 ‐ anions and the H 2 O molecules, parallel to (a, b) planes and situated at z = 0 and z = 1/2. The interlayer spacing is occupied by the organic molecules which perform different interactions around the 3D network cohesion. A characterization of this compound by solid‐state ( 13 C, 31 P) MAS NMR and IR spectroscopies is also reported. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
