A Ferromagnetically Coupled, Bell-Shaped [NiGd] Cage.

Reaction between NiCl·6HO, 2-hydroxy-4-methyl-6-phenyl-pyridine-3-amidoxime (HL), benzoic acid, and M(NO)·6HO (M = Gd, Y) in MeCN under basic conditions yields the complexes [NiGd(PhCOO)(HL)(HL)(OH)(NO)]Cl·13.6MeCN·HO (·13.6MeCN·HO) and [NiY(PhCOO)(HL)(HL)(OH)(NO)(HO)]0.

Constructing Cr-centered heterometallic complexes: [NiCr] and [CoCr] wheels.

The solvothermal reaction between Cr(acac), MCl·6HO (M = Ni, Co) and 2-hydroxy-4-methyl-6-phenyl-pyridine-3-amidoxime (HL), under basic conditions, led to the synthesis of the heterometallic heptanuclear clusters [MCr(HL)(HL)]·3Cl (M = Ni, 1; Co, 2), with the nickel analogue displaying an S = 9/2 spin ground-state.
