During complex formation donor species is called ligand, ligand act as lewis base in complex formation reaction, donor atom of ligands generally have lone pair and produce metal-donor atom linkage.
Total number of N-Co-O bond angles in one molecule of Pentaamminehydroxidocobalt(III) hexanitrito-Ncobaltate(III)
Answer:
Solution:
To find the total number of N–Co–O bond angles in Pentaamminehydroxidocobalt(III) hexanitrito-N-cobaltate(III):
Identify the ions and formula: The cation is and the anion is . To form a neutral molecule, they combine in a ratio: .
Count angles in the cation: In each octahedral ion, there are 5 Nitrogen atoms and 1 Oxygen atom directly bonded to the central Cobalt atom, creating exactly 5 N–Co–O bond angles.
Count angles in the anion: In , all ligands are bonded through Nitrogen, so there are 0 direct N–Co–O coordination angles.
Calculate total: Multiplying the angles per cation by the number of cations gives: .
