A high-spin cyanide-bridged Mo6Mn9 cluster: crystal structure and magnetism

A heterotrimetallic synthetic approach in versatile functionalization of nanosized {MxCu13–xW7}3+ and {M1Cu8W6} (M = Co, Ni, Mn, Fe) metal–cyanide magnetic clusters

The addition of 3d metal heteroatom into Cu^II(Me₃tacn)[W(CN)₈]ⁿ⁻ cluster system governs its structural and magnetic features.

Photoswitchable CuMoIV and CuMoIV cyanido-bridged molecules

The self-assembly of copper(ii) complexes with two Schiff base ligands: L1_O = N₃ and L2 = N₄ and octacyanidomolybdate(iv) ions yields two discrete molecules of odd nuclearity, namely pentametallic [Cu(L1_O)(py)]₄[Mo^IV(CN)₈]·14H₂O (1), Cu₄Mo and trimetallic [Cu(L2)]₂[Mo^IV(CN)₈]·9H₂O (2), Cu₂Mo. Both molecular systems have been characterised structurally and magnetically, revealing a photomagnetic effect. In the case of (1) a metal-to-metal charge transfer (MMCT) mechanism is proposed. The analysis of magnetic interactions in the photogenerated state of (1) assumes the formation of the metastable cluster CuCu^IMo^V where metal centres in Mo^V-CN-Cu^II linkages are ferromagnetically coupled with J₂ = 104(3) cm^-1. In (2) the increase in the magnetisation is due to the singlet-triplet transition on the Mo^IV centre leading to the formation of the metastable CuMo. The presence of the paramagnetic Mo (S = 1) centre linking the Cu^II (S = 1/2) centres allows for effective ferromagnetic interaction of 3 paramagnetic centres with coupling constant J₂ = 20.2(7) cm^-1.

The solvent effect on the structural and magnetic features of bidentate ligand-capped {CoII9[WV(CN)8]6} single-molecule magnets

Cyanido-bridged {Co^II₉W^V₆} clusters combined with 2,2′-bipyridine N-oxide produce three crystalline phases with different solvents affecting their structural and magnetic properties.
