A salt contains one trivalent metal M, potassium and six nitrite units per formula. It produces four ions per formula unit on complete dissociation, with total positive ionic charge +3 and total negative ionic charge −3. All six nitrites are coordinated monodentately; M is low-spin d⁶. Which follow? Count donor-mode/geometrical forms in an ideal octahedron.
Options:(select one or more)
Answer:
A, B, C
Solution:
Three K⁺ ions and one complex anion account for four particles and charges ±3. M³⁺ plus six nitrites gives −3. Low-spin d⁶ is paired. N-bound ligand counts 0…6 give 1,1,2,2,2,1,1 geometrical forms, total ten. None of the binary monodentate Ma₆₋ₖbₖ arrangements is chiral, so D is false.
