It outlines key crystallographic concepts, the theoretical principles of X-ray scattering, and data processing workflow using APEX and SHELXL. The experimental section describes crystal selection, data collection, integration, scaling, space-group determination and structure refinement. The results show how structural parameters of the ruthenium complex were solved, refined, and validated through refinement commands, quality indicators and standard crystallographic validation tools.27 pagesenX-ray Diffraction, Crystallography, Structure Refinement.ChemistryHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
