Octacyanometalate-based ferrimagnetic M(V)Mn(III) (M = Mo, W) bimetallic chain racemates with slow magnetic relaxations.

Cyanide-bridged M(V)-Mn(III) (M = Mo, W) bimetallic chain complexes with racemic spatial dispositions were constructed by self-assembling [M(CN)(8)](3-) precursors and Mn(III) Schiff bases. Antiferromagnetic couplings between spin centers within a chain result in a ferrimagnetic nature, and slow magnetic relaxations are observed as well.

Cyanide-bridged one-dimensional ferromagnetic Ru(III)Mn(III) coordination polymer exhibiting a field-induced magnetic phase transition.

A cyanide-linked Ru(III)(4d)-Mn(III)(3d) bimetallic chain complex (1) was prepared by the self-assembly of a ruthenium(III) bicyanide and a Mn(III) Schiff base. Ferromagnetic couplings between the magnetic centers are present within a chain, while antiferromagnetic interactions between chains (T(N) = 2.5 K) transmit.

Field-induced metamagnetic transition in the Fe(III)-Mn(III) bimetallic chain built by a new cyanide-bearing Fe(III) precursor.

The use of a new precursor, mer-[Fe(mpzcq)(CN)3]- (1), produced a dimeric molecule, [Fe(mpzcq)(CN)3][Mn(salen)(H2O)] x H2O (2), and a one-dimensional zigzag chain, [Fe(mpzcq)(CN)3][Mn(salcy)] x MeOH x MeCN (3). Antiferromagnetic couplings are operating between magnetic centers through CN ligands, and a field-induced metamagnetic transition is observed in 3.

Bimetallic M(V)(2)Cu(II)(3) (M = Mo, W) coordination complexes based on octacyanometalates: structures and magnetic variations tuned by chelated tetradentate macrocyclic ligands.

Four octacyanometalate-based bimetallic Cu-M (M = Mo, W) assemblies coordinated by tetradentate macrocyclic ligands were prepared via self-assembly process in a stoichiometric ratio of [M(CN)8]3- and Cu(macrocycle)2+ and characterized in terms of structures and magnetic properties. The crystal structures are varied depending on the macrocycles used. The employment of cyclam with no pendant groups produced a one-dimensional chain (1) with a rope-ladder pattern, whereas macrocycles with side groups allowed for the formation of two-dimensional honeycomb-like architectures (2-4).

Uncommon ferromagnetic interactions in a homometallic Co(II) chain bridged by a single end-to-end azide.

A new one-dimensional heterochiral coordination polymer [Co(bmdt)(N3)2].MeCN (1.MeCN) with well-isolated chains was prepared via a self-assembly process.

Ferrimagnetic FeIII-MnIII zigzag chain formed by a new mer-positioned ironIII cyanide precursor.

A new cyanide-bearing molecular precursor, mer-[Fe(pzcq)(CN)(3)]- (1), and a zigzag chain, [Fe(pzcq)(CN)(3)][Mn(salen)].4H(2)O (2), were prepared and characterized in terms of structure and magnetism. Magnetic data reveal that intrachain antiferromagnetic couplings via cyanide ligands in 2 are clearly operating, resulting in a ferrimagnetic nature.

Two WV-MnIII bimetallic assemblies built by octacyanotungstate(v) and MnIII Schiff bases: molecular structures and a spin-flop transition.

Two W(V)-Mn(III) bimetallic compounds, [Mn(Cl-salmen)(H(2)O)2]{[Mn(5-Clsalmen)(H(2)O)]2[W(CN)8].2H(2)O (1.2H(2)O) [5-Clsalmen = N,N'-(1-methylethylene)bis(5-chlorosalicylideneiminato) dianion], which contains trinuclear Mn(2)W and isolated Mn(III) moieties, and [Mn(3-MeOsalcy)(H(2)O)2]3[W(CN)(8)].
