Abstract Following reports of the synthesis and single crystal X‐ray structural characterization of adducts of simple group 1 metal salts with the N,N′ ‐aromatic bidentate ligands 2,2′‐bipyridine (‘bpy’), 1,10‐phenanthroline (‘phen’) and 2,9‐dimethyl,1,10phenanthroline (‘dmp’) (= L), of 1:1 and 1:2 MX : L stoichiometry in the preceding papers, adducts of 1:3 stoichiometry are described in the present, for M = Na, of the form [NaL 3 ]X(·S) representative of all L = bpy, phen, dmp. [Na(bpy) 3 ]I is of interest, the cation stereochemistry being essentially trigonal prismatic; in [Na(phen) 3 ](F 3 CSO 3 )·2MeOH, it is a more usual twisted octahedron, while, in [Na(dmp) 3 ]I·MeOH, in consequence, presumably, of constraints imposed by the ligand substituents, a novel array of quasi‐ m symmetry, with out‐of‐plane coordination of the metal atom, is found for the first structurally defined [M(dmp) 3 ] n± species. A hydrated adduct, KClO 4 : phen : H 2 O (1:5:6) is also described, being of the form [(phen) 3 K(μ‐OH 2 ) 2 K(phen) 3 ](ClO 4 ) 2 ·4phen·4H 2 O, the unusual stereochemistry about the metal atom presumably strongly influenced by packing effects as is the lattice array itself.
