摘要

A polynuclear silver(I) complex {[(t-Bu)(4)N](2)[Ag6I8]}(n) 1 with iodo-bridging ligands has been prepared, the centrosymmetric cluster anion can be described as two [Ag4I4] distorted cubane units sharing one [Ag2I2] plane. This cluster polymer shows strong third-order nonlinear optical (NLO) absorption and refraction with absorption coefficient alpha(2) = 8.9 x 10(-10) m(.)w(-1) and refractive index n(2) = -6.6 x 10(-17) m(2 .)w(-1).
