A novel metal‐organic coordination complex crystal: tri‐allylthiourea zinc chloride (ATZC)

Abstract

A new metal-organic coordination nonlinear optical crystal, tri-allylthiourea zinc chloride (ZnCl 2 (AT) 3 , where AT is CH 2 =CHCH 2 NHCSNH 2 , abbreviated as ATZC), is reported. It was synthesized in water and recrystallized in ethanol. For the crystal structure, optical and thermal characterization were determined by elemental analyses, X-ray diffraction, infrared spectroscopy, differential scanning calorimeter, thermogravimetric analysis, and powder SHG efficiency meansurement. It belongs to the trigonal system, space group R3, with a=11.0498(4)Å, c= 16.0416(11)Å, z=3 and V=1696.24(15)Å 3. It exhibits powder SHG efficiency the same order as Urea crystal.

Synthesis, growth and characterization of an organometallic complex tri-allylthiourea cadmium bromide single crystals

“…The lattice parameters evaluated using the measured 2h values are given in Table 1. The values agree well with the single crystal diffraction results and also with the results, reported for allylthiourea co-ordination compounds [13,14,17].…”

“…4) of ATCB crystal was recorded in the region 400-4000 cm À1 . Generally, the molecular structures of thiourea derivatives have characteristic resonance [13]. They highly favour sulfur co-ordination to the metal when forming complexes with metal halides.…”

“…They have the general formula M (CH 2 @CH-CH 2 NHCSNH 2 ) 3 X 2 , (M = Cd, Hg; X = Cl, Br). Recently, synthesis and growth of new members of ATMX series of organometallic co-ordination complexes; tri-allylthiourea zinc chloride (ATZC) [13] and tri-allylthiourea zinc bromide (ATZB) [14] were reported. Allylthiourea complexes have relatively large NLO co-efficient and excellent UV cut-off wavelengths [15].…”

Synthesis, Microhardness, FT-IR, and Thermal Decomposition of Semiorganic Antimony Thiourea Bromide Monohydrate Single Crystals

“…Single crystals of some inorganic complexes of thiourea are gaining importance in recent years because of their unique optical properties [1][2][3]. The thiourea molecule is an interesting inorganic matrix modifier due to its large dipole moment [4] and its ability to form an extensive network of hydrogen bonds.…”

Synthesis and Characterization of L-Alanine Sodium Bromide: A New Semi Organic Nonlinear Optical Material

“…In addition to large second order susceptibilities, good transmission in UV and visible region and stable physio-thermal performance are needed for these applications [11,12]. Inorganic NLO materials have large mechanical strength, thermal stability and good transmittance but modest optical nonlinearity due to the lack of extended π -electron dislocation [13,15]. Purely organic NLO material have large nonlinearity compared to inorganic material but low optical transparency, poor mechanical and thermal strength and low laser damage threshold .…”
