Synthesis and crystal structure of a new inorganic – organic complex: (4‐ClC 7 H 6 NH 3 ) 9 [Nd(P 6 O 18 ) 2 ]·9H 2 O

Single crystals of (4‐ClC 7 H 6 NH 3 ) 9 [Nd(P 6 O 18 ) 2 ]·9H 2 O were synthesized in aqueous solution. This compound crystallizes in a triclinic P1 unit‐cell, with a = 14.898(6), b = 18.049(7), c = 20.695(6)Å, α = 102.04(3), β = 100.49(3), γ = 98.82(3)°, V = 5245(4) Å 3 and Z = 2. The crystal structure has been solved and refined to R = 0.043 (Rw = 0.061) for 20420 observed reflections. The atomic arrangement of the title compound can be described as infinite layers built by complex of Neodyme [Nd(P 6 O 18 ) 2 ] and nine water molecules. The organic cations are located in the space delimited by the successive inorganic layers. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
