Novel heterometallic metal–azido complex synthesized by “one-step” reaction: synthetic strategy and magnetic properties

• It is difficult to construct simple coordination complexes with azide as “ligands” to obtain heterometallic metal–azido compounds.
• A “one-step” method—hydrothermal reaction— was introduced to avoid the disadvantages of azide mentioned above.
• The magnetic property is different with the isostructural homometal–azido complex due to the changed metal center.

A novel heterometallic complex, [Ni2Mn(N3)2(nic)4·(H2O)2]n (1) (nic=nicotinate), was obtained by assembling MnCl2·4H2O, Ni(NO3)2·6H2O, NaN3 and nicotinic acid with a “one step” synthetic strategy—hydrothermal reaction. The 3D structure of the complex can be described as end-on (EO) azido and syn,syn carboxylates mixed bridged by alternate Ni–Mn–Ni trimers linked by the nicotinate. Dominant ferromagnetic interactions were observed between the NiII and MnII ions in the trimer.
