Magnetic behavior and ground spin states for coordination {L·[M(Hal)]} assemblies (Hal = Cl or I) of radical trianion hexacyanohexaazatriphenylenes (L) with three coordinated high-spin Fe ( = 2) or Co ( = 3/2) centers.

A series of trianion assemblies of hexaazatriphenylenehexacarbonitrile {HAT(CN)} and hexaazatrinaphthylenehexacarbonitrile {HATNA(CN)} with three Fe(II) or Co(II) ions: {cryptand(K)}·{HATNA(CN)·(FeI)}·2CHCl (1), {cryptand(K)}·{HATNA(CN)·(CoI)}·2CHCl (2), and (CV)·{HAT(CN)·(CoCl)}·0.5(CVCl)·2.5CHCl (3) are synthesized (CVCl = crystal violet).

Trinuclear coordination assemblies of low-spin dicyano manganese(II) ( = 1/2) and iron(II) ( = 0) phthalocyanines with manganese(II) acetylacetonate, tris(cyclopentadienyl)gadolinium(III) and neodymium(III).

The reaction of MnPc, FePc or FePcCl with KCN in the presence of cryptand[2.2.2] yielded dicyano-complexes {cryptand(K)}{M(CN)(macrocycle)}·CHCl (M = Mn and Fe, = 1 and 2) that were used for the preparation of trinuclear assemblies of the general formula {cryptand(K)}{M(CN)Pc·(ML)}·CHCl (M = Mn and Fe; = 1, 4 and 5).

Weak Antiferromagnetic Exchange and Ferromagnetic Alignment of Fe (S=2) Spins in Differently Charged {HAT ⋅ (Fe Cl ) } (n=2- and 3-) Assemblies of Hexaazatriphenylenes (HAT).

Hexaazatrianthracene (HATA) and hexaazatriphenylenehexacarbonitrile {HAT(CN) } are reduced by metallic iron in the presence of crystal violet (CV )(Cl ). Anionic ligands are produced, which simultaneously coordinate three Fe Cl to form (CV ) {HATA ⋅ (Fe Cl ) }  ⋅ 3 C H Cl (1) and (CV ) {HAT(CN) (Fe Cl ) }  ⋅ 0.5CVCl ⋅ 2.
