Crystal growth and physical properties of UV nonlinear optical crystal zinc cadmium thiocyanate, ZnCd(SCN)4

Abstract Zinc cadmium thiocyanate, ZnCd(SCN) 4 (ZCTC) single crystals of optical quality have been grown from aqueous solution by controlled evaporation at 40 °C. The morphology of the crystal was indexed. Raman spectroscopy, refractive indices, optical transmission and optical damage threshold of the ZCTC crystal were all performed at room temperature. Violet and ultraviolet (UV) light output by frequency doubling of a 808 nm GaAlAs laser diode and a continuous wave Ti:sapphire laser at 760 nm were achieved. The dielectric constants, piezoelectric strain constants, electroptic coefficients, and direct current resistivities have also been measured.

Manganese mercury seleno­cyanate, MnHg(SeCN)4

MnHg(SeCN)4 has a three-dimensional network in which slightly distorted MnN4 and HgSe4 tetraxadhedra (symmetry overline{4}) are connected by –SeCN– bridges.

Poly[bis(sulfolane-κO)di-μ2-thio­cyanato-cadmium(II)]

In the title complex, [Cd(SCN)2(C4H8O2S)2]n, the CdII atom, on an inversion centre, is within a distorted N2S2O2 octaxadhedron and the five-membered ring has a distorted envelope conformation. In the crystal structure, neighbouring Cd atoms are connected by –SCN– bridges, leading to the formation of an infinite three-dimensional –Cd–NCS–Cd– network.
