Crystallizations of simple group 1 metal salts MX with N,N′ ‐bidentate aromatic ligands 1,10‐phenanthroline (‘phen’) and the hindered 2,9‐dimethyl,1,10‐phenanthroline (‘dmp’), as well as complexes of other forms and stoichiometries described in accompanying papers, have yielded a broad array of simple mononuclear adducts of 1:2(:n) MX : L (:S) stoichiometry from methanol solutions. One of these, NaBr : phen : MeOH (1:2:2) contains a six‐coordinate metal atom, being ionic [(Me O H) 2 Na(phen) 2 ]Br, but the majority contain five‐coordinate metal atoms, being either ionic (one example only, [(Me O H)Li(phen) 2 ]Cl·MeOH) or neutral [XML 2 ] species, the latter for the combinations MX : phen (M = Li, X = I, ClO 4 , tfs (≡ ‘triflate’, F 3 CSO 3 ) (a new form), NO 3 ; M = Na, X = Br, I, ClO 4 , NO 3 ) and MX : dmp (M = Na, X = N CS, Br, I, PF 6 , ClO 4 ; M = K, X = I), the (coordinating) polyatomic anions being unidentate, and the coordination geometries distorted trigonal bipyramidal.
