Summary of main observation and conclusion Self‐assembly of the [Mo(CN) 7 ] 4– anion and the Mn 2+ ion in the aqueous solution containing ammonium formate results in a new coordination polymer, {(NH 4 ) 3 [(H 2 O)Mn 3 (HCOO)][Mo(CN) 7 ] 2 ·4H 2 O} n . Single crystal X‐ray analysis revealed a very complicated three‐dimensional (3D) framework, where both the [Mo(CN) 7 ] 4– and the formate anions act as bridges between the Mn II centers. Magnetic measurements revealed that this compound displays ferrimagnetic ordering below 70 K. Competing antiferromagnetic interactions between the spin carriers might lead to spin frustration and non‐linear alignment of the magnetic moments. Specifically, this compound is the first mixed [Mo(CN) 7 ] 4– /HCOO – bridged molecule magnet.
