[en] The crystal structure of the [(Cl₃PO)₆ Nd(μ-O₂PCl₂)₂ SnCl₄]SnCl₅x2POCl₃ compound, from NdCl₃-OPCl₃-SnCl₄ laser liquid is determined. The elementary cell parameters equal a=21.58(2), b=12.28(1), c=12.25(1)A, α=92.08(8), β=96.28(7), γ=91.24(6) deg, v=3223.3 A³. The [(Cl₃PO)₆ Nd (μ-O₂PCl₂)SnCl₄]⁺ complex cation consists of eight-term metallocycle, including Nd atom, two dichlorophosphate ions and one Sn atom, as well as of six phosphorus oxychloride molecules, coordinated through O atom near Nd atom. Coordinated polyhedrons of Nd atom are double-cap trigonal prism with O atoms in the peak. The interatomic distances and bond angles are determined
