Cs 23 Mn 16 O 23 was synthesized via the azide/nitrate route from mixtures of Mn 2 O 3 , CsNO 3 , and CsN 3 . This manganese(II/III) mixed‐valent oxide, which contains only one Mn 3+ besides 15 Mn 2+ cations, was studied by single‐crystal X‐ray diffraction and magnetic susceptibility measurements. Its crystal structure [ P 1 , Z = 1, a = 1114.26(2), b = 1185.53(2), c = 1205.39(2) pm, α = 70.596(1), β = 80.377(2), γ = 83.072(2)°, R 1 = 0.033] is based on a honeycomb‐like arrangement of cesium atoms, providing the space for two different types of one‐dimensional polyoxomanganate anions, illustrated by the syntax Cs 23 [MnO 2 ] 4 [Mn 3 O 5 ] 4 . Magnetic susceptibility measurements indicate dominant antiferromagnetic intra‐chain interactions present already at ambient temperature and long range inter‐chain magnetic ordering at 11 K.
