Abstract

Chemistry of rare earth metals coordination complexes has a potential as a material for teaching and learning sustainable chemistry principles. System thinking has an important role to link the chemistry of rare earth metals coordination complexes to the principle of sustainability. This study was conducted to obtain scientist conception about chemistry of rare earth metals coordination complexes as sustainable material that emphasized enhancement students’ system thinking ability. The Method used is qualitative content analysis (inductive literature review type). It is includes the collection of research articles, descriptive analysis, category selection and material evaluation based on didactical view. The instrument used is a content analysis format related to the concept of rare earth metals coordination complexes. The results showed that the scientist’s conception of rare earth metals coordination complexes can be analyzed to qualitative with used inductive approach. The scientist’s conception was obtained which are important concepts such as synthesis, characterization, and application of material based on rare earth metals. The synthesis of coordination complexes is carried out using central atoms in the form of metals and/or rare earth ions with several ligands. The characterization of complexes compound conducted to determine their solubility, crystal structure, and physicochemical properties. Based on its application reviewed, chemistry of coordination complexes showed environmentally safe properties, society, and increase economic value.
