“…During the past several decades, the investigation of the crystal growth and performance of novel organometallic NLO crystals, especially those exhibiting excellent second-order nonlinearities, has attracted very considerable interest [2][3][4][5][6][7][8][9][10][11][12]. Among them, cadmium mercury thiocyanate (CMTC) crystal has been thought of as a perspective second order NLO crystal which exhibits high second harmonic generation (SHG) efficiency and wide transparency wavelength regions down to 372 nm [6][7][8][9].…”

A novel potentially useful second harmonic generation (SHG) organometallic nonlinear optical (NLO) crystal: cadmium mercury thiocyanate bis(N-methylformamide), CdHg(SCN) 4 (C 2 H 5 NO) 2 (CMTN), has been prepared, and large high-optical-quality single crystals with dimensions up to 30 ×27 × 9 mm 3 have been grown by the temperature-lowering method. Its structural, physicochemical and optical properties are characterized by elemental analyses, X-ray powder diffraction, Fourier transform infrared and Raman spectroscopy, thermal analysis, powder SHG measurements and UV/Vis/NIR transmission. The specific heat has been determined to be 515.5 J mol −1 K −1 at 300 K. CMTN possesses good physicochemical stability up to 128.5 • C, exhibits powder SHG efficiencies 0.8 times that of urea and its UV transparency cutoff is 358 nm. By the use of the DFT/B3LYP/6-31G(d) method, the microscopic second order NLO behavior of CMTN has been investigated by computing the first-order hyperpolarizability together with that of CdHg(SCN) 4 (CMTC) and CdHg(SCN) 4 (C 3 H 8 O 2 ) (CMTG) crystals. The results have been explained based on their crystal structures.

Combining a strong second‐order nonlinear optical (NLO) effect (>1×KH2PO4 (KDP)), a large bandgap (>4.2 eV), and a moderate birefringence in ultraviolet (UV) NLO crystals remains a formidable challenge. Herein, Cd(SCN)2(C4H6N2)2, the first example of a thiocyanate capable of realizing a phase‐matched UV NLO crystal material, is obtained by reducing the sulfur (S) content in the centrosymmetric (CS) structure of Cd(SCN)2(CH4N2S)2. Compared to the "shoulder‐to‐shoulder" one‐dimensional (1D) chain of Cd(SCN)2(CH4N2S)2, Cd(SCN)2(C4H6N2)2 has a different sawtooth 1D chain structure. Cd(SCN)2(CH4N2S)2 has second harmonic generation (SHG) inertia with a bandgap of 3.90 eV and a UV cutoff edge of 342 nm, however, it possesses a large birefringence (0.35@546 nm). In contrast, the symmetry center breaking of Cd(SCN)2(C4H6N2)2 leads to remarkably strong SHG intensity (10 times that of KDP). Furthermore, it has a wide bandgap (4.74 eV), short UV cutoff edge (234 nm), and moderate birefringence capable of phase matching (0.17@546 nm). This research indicates that thiocyanates are a promising class of UV NLO crystal materials, and that modulation of the sulfur content of CS thiocyanates is an effective strategy for the development of UV NLO crystals with excellent overall performances.
