The synthesis of ionic complexes of cadmium(II) chloride and cobalt(II) chloride with N,N'-diethylthiourea (detu) ligands has not been previously reported. Therefore, in this research, the synthesis was carried out to study the structure and characterization of the two ionic complex compounds. The cadmium(II)-detu ionic complex was synthesized using the direct reaction method with a ratio between Cd(II) salt and detu ligand of 1:2. Meanwhile, the cobalt(II)-detu ionic complex was synthesized with a ratio between Co(II) salt and detu ligand of 2:4. The cadmium(II)-detu and cobalt(II)-detu ionic complexes have melting points of 105-108 ˚C and 122-125 ˚C, respectively. The electrical conductivity of the cadmium(II)-detu and cobalt(II)-detu complexes showed that the complexes were ionic. The FTIR analysis showed the shifting of the C=S functional group’s band to the smaller wavenumber, which indicates the coordinating detu ligand to the cadmium(II) and cobalt(II) through the S atom. The indirect evidence from 1H-NMR showed that CH3 and CH2 only slightly shifted between the free detu ligand and the Cd-detu and Co-detu complexes.

The development of complex compounds as antibacterial continues to be carried out to overcome cases of microbial resistance. One of them is the development of complex compounds with thiocyanate and aminopyridine ligands which show good potential as antibacterial. Complex compound of zinc(II) chloride with thiocyanate and 2-aminopyridine ligands was successfully synthesized. The synthesis was carried out by mixing the reactants with ratio of Zn2+: 2-aminopyridine: SCN 1:2:2 under heating and stirring continuously for 6 hours. The Obtained beam-shaped colorless crystals were characterized using melting point, electrical conductivity, thiocyanate ion qualitative, FTIR, SEM-EDX, XRD powder and antibacterial activity against Salmonella typhi and Staphylococcus aureus test. The crystals melt at 160-165 0C. The results of the electrical conductivity test, qualitative test of thiocyanate ion, FTIR and SEM-EDX analysis indicate the presence of Zn2+, thiocyanate and 2-aminopyridine with ratio 1: 2: 2. Based on XRD powder spectral data and theoritical analysis, the complex synthesized compounds had high crystallinity and predicted has tetrahedral structure. Antibacterial test showed that against S.aureus, the compound had higher antibacterial activity than free ligands, but lower than chloramphenicol. Therefore, the antibacterial activity of the complex compound was classified as moderate.

The voltaic cell teaching materials used in high school are still in the form of textbooks that do not present multiple representations of chemistry, namely the macroscopic, submicroscopic, and symbolic levels. The three levels of chemical representation can be visualized using flipbook teaching materials so that students are expected to understand the voltaic cell material. Teaching materials are used to support the learning process. Current learning still uses conventional learning models that only focus on teachers. Constructivist-based active learning is needed because it involves students so that learning is more meaningful. One of the constructivist learning models is the guided inquiry learning model which includes observing, asking questions, compiling hypotheses, gathering information, testing hypotheses, and concluding. The purpose.of this development.is to.produce a proper guided inquiry-based flipbook teaching material. The flipbook teaching.materials were developed.using the Four-D model (define, .design, .develop,and.disseminate) but the disseminated stage was not carried out. Media and material validation was carried out by five chemistry lecturers. The legibility test was carried out by 50 high school alumni with a specialization in Science. The assessment uses a Likert scale accompanied by comments, suggestions from the validator, and audience.
