“…Hasil uji FTIR dari ligan detu serta senyawa kompleks yang disintesis ditunjukkan pada Gambar 1 kemudian ditabelkan pada Tabel 3. Pergeseran frekuensi rendah pada pita υ(C=S) dan pergeseran frekuensi tinggi pada pita υ(N-H) menunjukkan adanya thione dari detu (Wahyuni, 2021). Ikatan υ(N-H) sekunder ligan detu teramati pada bilangan gelombang sekitar 3225-3435 cm -1 .…”

Senyawa kompleks dari garam nikel dengan ligan N,N'-dietiltiourea (detu) perbandingan mol 1:4 berhasil disintesis dan dikarakterisasi dengan metode reaksi langsung dan refluks. Kompleks Ni-detu(DR) dan Kompleks Ni-detu(R) yang secara berurutan disintesis dengan metode langsung dan refluks mempunyai titik lebur 159-161°C dan 114-116°C. Analisis data FT-IR kedua sampel menunjukkan ikatan υ(N-H) Ni-detu berada pada rentang 3233-3235 cm -1 , υ(C-H) 2964-2974 cm -1 , υ(C-N) 1562-1579 cm -1 , dan υ(C=S) 646-653 cm -1 . Analisis refinement data XRD diperoleh Rwp sebesar 11,63% menunjukkan senyawa yang terbentuk mempunyai kemiripan struktur dengan senyawa kompleks [Ni(detu)4]Cl2. Hasil pengukuran VSM pada kompleks hasil sintesis Nidetu(DR) dan Ni-detu(R) menujukkan keduanya bersifat diamagnetik.

“…After 10 days of evaporation, colorless and shiny needle crystals were formed. Complex compounds with the central atom in closed cell groups are colorless because the d orbitals are completely filled with electrons, so there are no d-d transitions that cause colored complex compounds (Setiawan et al, 2017).…”

Cadmium (II) halides with N,N'-diethylthiourea (detu) ligands at a stoichiometry of 1: 2 tend to form molecular complexes [Cd(detu)2X2] with a distorted tetrahedral geometry at the central atom. Generally, these complex compounds are prepared by the conventional method of reflux for 4 hour. The use of ultrasonic waves for complex synthesis can be an alternative to make the reaction time more efficient and environmentally friendly. The aim of this study was to synthesize and characterize complex compounds from CdBr2 and detu ligands using the ultrasonication method that have not previously reported. The synthesis of complex compounds was carried out by reacting CdBr2 and detu (1:2) in methanol solvent. In the synthesized compounds, a melting point test, electrical conductivity test, Fourier Transform Infrared (FTIR), Scanning Electron Microscope-Energy Dispersive Xray (SEM-EDX), qualitative test of bromide ion and calculation of free energy using Spartan'14 software were carried out for the complex structure prediction. The complex compound resulted has colorless needle crystals with a melting point of 93-94°C. The results of the EDX analysis provide the empirical formula C10H24CdBr2N4S2. The electrical conductivity test data and the bromide ion qualitative test proved that the synthesized complex compound was a molecular complex compound with the molecular formula [Cd(detu)2Br2]. The complex compound has two possible structures, namely a distorted tetrahedral and a square planar. Free energy calculations showed that complex compounds with a distorted tetrahedral structure and a square planar have free energies of -527.5574 kJ/mol and -408.7424 kJ/mol, respectively.
