Crystal field theory describes the interaction between d orbitals and these species. For 10 points each:
[10e] Name these species that bind to transition metals in coordination complexes.
ANSWER: ligands
[10h] The binding of a ligand to an ion causes a decrease in this value in the nephelauxetic (“NEFF-ull-ox-ET-ic”) effect. This value, which approximates the strength of a metal–ligand bond, is the denominator of both axes of Tanabe–Sugano diagrams.
ANSWER: Racah B parameter [prompt on Racah parameter]
[10m] This ion induces the greatest nephelauxetic effect when used as a ligand. This weakest ligand on the spectrochemical series mimics the crystal structure of ice when bound to silver, making it useful for cloud seeding.
ANSWER: iodide [or I− (“I-minus”); accept silver iodide; prompt on iodine]
