Abstract

The reaction of Cu with a molten mixture of Cs₂S/P₂S₅ produced the quaternary compound Cs₂CuP₃S₉. The bright yellow crystals of Cs₂CuP₃S₉ are stable in air and water for several weeks. The compound crystallizes in the chiral, hexagonal space group P6₅ (No. 170) and at 23°C: a = 15.874(2) Å; c = 35.100(7) Å; V = 7660(3) Å³; Z = 18. The [CuP₃S₉](n)/(2n-) chains are composed of an alternating arrangement of tetrahedral Cu⁺ ions and cyclic [P₃S₉]^3- units. The structure contains parallel helical [CuP₃S₉](n)/(2n-) chains that run along the c-axis. The cyclic [P₃S₉]^3- unit derives from the molecular adamantane [P₄S₁₀] unit with one [PS]³⁺ vertex removed. The title compound was characterized by differential thermal analysis, far-IR, Raman, and single-crystal optical transmission UV/vis spectroscopy. Positive nonlinear optical response and second harmonic generation response was observed. (C) 2000 Academic Press.
