A novel heterometallic complex, [Ni{sub 2}Mn(N{sub 3}){sub 2}(nic){sub 4}·(H{sub 2}O){sub 2}]{sub n} (1) (nic=nicotinate), was obtained by assembling MnCl{sub 2}·4H{sub 2}O, Ni(NO{sub 3}){sub 2}·6H{sub 2}O, NaN{sub 3} 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 Ni{sup II} and Mn{sup II} ions in the trimer. - Graphical abstract: A novel heterometallic 3D complex [Ni{sub 2}Mn(N{sub 3}){sub 2}(nic){sub 4}·(H{sub 2}O){sub 2}]{sub n} (1) (nic=nicotinate) was synthesized by hydrothermal reaction. This complex exhibits interesting structural and magnetic properties. - Highlights: • 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.
