The resulting DUV all-solid-state laser has important applications in cutting-edge technological fields such as medical, micromachining, lithography, photochemistry, spectroscopy, and microscopy. In the deep-ultraviolet (DUV) spectral region with wavelengths shorter than 200 nm, NLO crystals are the core devices for realizing high-power DUV laser output. NLO crystals are basic materials for realizing NLO technology. Nonlinear optical (NLO) technology is an important means to extend the wavelength of laser. Nonlinear optics plays an important role in modern optics and laser technology.

Such a remarkable difference in the NLO property may be due to the fact that iodide is a better electron donor than bromide, which allows more efficient spin-orbital coupling, and facilitates intersystem crossing and more efficient usage of triplet excited state absorption. Compound 1 exhibited relatively strong NLO responses while compound 2 showed nothing.

The third-order nonlinear optical (NLO) behaviours of 1 and 2 in DMF were investigated by using femtosecond degenerate four-wave mixing technique.

Such a difference in structural symmetry between 1 and 2 may be due to the fact that the radius of iodide is larger than that of bromide. Although compounds 1 and 2 have similar chemical formula, 1 crystallizes in the orthorhombic space group Ima2 and holds a 1D non-centrosymmetric zigzag chain while 2 crystallizes in the orthorhombic space group Pnma and has a 1D centrosymmetric zigzag chain. In the structures of 1 and 2, the ppt ligand was in situ generated from the Hg(II)-engaged cleavage of both S-S and S-C bonds of dpds and the subsequent rearrangement reactions under solvothermal conditions.

Solvothermal reactions of HgX 2 (X=I, Br) with 4,4'-dipyridyl disulfide (dpds) in acetonitrile gave rise to two one-dimensional polymers n.
