“…The absorption peak around 1542 nm in the transmittance spectrum may be attributed to the second harmonic peak of the N-H stretching vibrations. In the wavelength range from 500 to 1500 nm, the transmittance of the grown powder crystal is ~ 85% on average, which is about two times greater than that of α-BTC [17] at the same wavelength range.…”

“…In the range of 500-2500 nm, DCBPB crystal exhibits a relatively good transmittance, whereas, in the window of 500-1500 nm, DCBPB crystal shows excellent transmittance. In contrast, α-BTC [17] has a distinguish absorption at ~ 800-1300 nm. The absorption peak around 1542 nm in the transmittance spectrum may be attributed to the second harmonic peak of the N-H stretching vibrations.…”

“…In step 1, there was a 28% reduction in weight, which is mainly due to the release of some inorganic nonmetal gas produced by the decomposition of DCBPB crystals, such as CS 2 , COS, or NH 2 CN [25,26]. In step 2, the further weight loss at 536 °C is attributed to the volatilization and oxidation of remaining products including the carbon oxides, sulfide, or bismuth chloride [17]. …”

“…DCBPB belongs to a triclinic system, with the P1 space group, which is different from the reported bismuth thiourea chlorides α-BTC (monoclinic, Cc) [17] and β-BTC (hexagonal, P3) [18]. The unit cell of DCBPB crystal ( Fig.…”

“…Besides, coordinating thiourea with metal halide can provide acentric symmetrical structure, which is required to produce a high-optical transparent NLO crystal with a large nonlinear coefficient [13]. In the past 20 years, several thiourea-based semi-organic NLO compounds have been discovered, such as bis-thiourea cadmium chloride (BTCC) [14], zinc thiourea chloride (ZTC) [15], zinc thiourea sulfate (ZTS) [16], α-bismuth thiourea chloride (α-BTC) [17], β-bismuth thiourea chloride (β-BTC) [18], and bismuth thiourea chloride dihydrate (TBNTNC) [19].…”

Crystals of a new organometallic nonlinear optical (NLO) compound, di-μ-chloro-bis[chlorotri(thiourea)bismuth(III)]-pentachloro(thiourea)bismuth-ate(III) (DCBPB), have been successfully grown from formic acid aqueous solutions of thiourea and bismuth chloride by a slow evaporation technique. The crystal structure and atomic composition of DCBPB have been confirmed by single crystal X-ray diffraction (SCXRD), Fourier transform infrared spectra, and elemental analysis. The SCXRD results proved that DCBPB crystallizes in triclinic space group P1 with unit cell dimensions of a = 7.0606(2) Å, b = 8.8106(4) Å, c = 16.3247(8) Å, α = 99.242(4)°, β = 95.309(3)°, γ = 105.856(3)°, and Z = 2. DCBPB crystal exhibits excellent transmittance from 500 to 2500 nm and green fluorescence with maximum emission at 508 nm. The thermogravimetricdifferential scanning calorimetry (TG-DSC) analysis indicates that a solid-phase reaction took place at 170.1 °C, whereas the decomposition temperature of the crystal material was 189 °C. The NLO property obtained by the Kurtz powder test showed that the second harmonic generation efficiency of DCBPB crystal is two-seventh of KDP crystal.

A series of crystals of bismuth thiourea iodide (Bi[CS(NH2)2][CS(NH2)2H]2I5, Bi[CS(NH2)2H]3I6, and Bi[CS(NH2)2H]6I9) have been successfully grown from hydroiodic acid solution of thiourea and bismuth oxide by slow evaporation technique. Interestingly, they exhibit distinct crystal structures resulting from the proton effect on the cation coordination. Single crystal X‐ray diffraction reveals that they belong to three different crystal systems, P21/c for Bi[CS(NH2)2H]3I6, Rtrue3‾ c for Bi[CS(NH2)2H]6I9, and only Bi[CS(NH2)2][CS(NH2)2H]2I5 into a noncentrosymmetric space group Pca21, with unit cell dimensions of a=15.755(3) Å, b=9.3257(19) Å, c=14.855(3) Å, and Z=4. It is observed that thiourea molecules in Bi[CS(NH2)2][CS(NH2)2H]2I5 adopt a novel coordination mode with central ions in which they can be classified into two parts: the ones which coordinate with the central metal ions and the protonated ones which are isolated in the crystal lattice. Meanwhile, all the thiourea molecules are protonated in Bi[CS(NH2)2H]3I6, and the central Bi3+ coordinates only with I− as the acidity increases. Furthermore, central Bi3+ in Bi[CS(NH2)2H]6I9 employs the similar coordination mode with Bi[CS(NH2)2H]3I6. However, more thiourea molecules are protonated (up to 6 protonated thiourea molecules vs. 3 ones in Bi[CS(NH2)2H]3I6) as the acidity keeps increasing. It is noteworthy that acidity is confirmed to be the key factor of crystallization and crystallographic structures. Thermal analysis shows that all compounds have high thermal stability up to 180 oC. In addition, optical characterizations such as FTIR, diffuse reflectance spectra and NLO test are also conducted.
