For the first time aqua pentafluoro manganate(III) compounds with different organic N‐cations have been prepared and their crystal structures have been determined: N,N′‐DMenH 2 [MnF 5 (H 2 O)] · H 2 O 1 (N,N′‐DMen = N,N′‐Dimethylethylenediamine), space group P2 1 /c, a = 916.0, b = 1004.8, c = 1247.9 pm, β = 106.03°, R = 0.035; NMpipzH 2 · [MnF 5 (H 2 O)] · H 2 O 2 (NMpipz = N‐Methylpiperazine), space group P2 1 /n, a = 757.7, b = 1261.9, c = 1197.1 pm, β = 105.09°, R = 0.027; N,N′‐DMpipzH 2 [MnF 5 (H 2 O)] · 2 HF 3 (N,N′‐DMpipz = N,N′‐Dimethylpiperazine), space group P1, a = 677.1, b = 863.9, c = 1187.7 pm, α = 79.18°, β = 81.63° γ = 67.62°, R = 0.026; and N,N‐DMenH 2 [MnF 5 (H 2 O)] · 1/2 HF 4 (N,N‐DMen = N,N‐Dimethylethylenediamine), space group P1, a = 859.3, b = 1086.5, c = 1092.0 pm, α = 86.96°, β = 78.52° γ = 89.01°, R = 0.035. In all compounds the [MnF 5 (H 2 O)] 2– octahedra are connected via H‐bonds forming 3 D and 2 D network arrangements. The anions are strongly elongated by the Jahn‐Teller effect. The FTIR spectra are presented.
