Nonlinear optical and ferroelectric properties of a 3-D Cd(II) triazolate complex with a novel (6(3))2(6(10) x 8(5)) topology.

A novel 3-D (3,6)-connected topological architecture, obtained by reacting Cd(ClO4)2 x 6H2O with Htrtr (Htrtr = 3-(1,2,4-triazole-4-yl)-1H-1,2,4-triazole) under solvothermal conditions, presents a non-centrosymmetric polar packing arrangement, resulting in a strong second harmonic generation (SHG) response and ferroelectric property.
