Abstract: | The crystal structure of the title compound, tetrachloroμ‐1,1,4,7,7‐pentakis(1H‐benzimidazol‐2‐ylmethyl)‐1,4,7‐triazaheptane]dimanganese(II) methanol pentasolvate tetrahydrate, Mn2Cl4(C44H43N13)]·5CH4O·4H2O, contains an asymmetric dinuclear MnII–DTPB DTPB is 1,1,4,7,7‐pentakis(1H‐benzimidazol‐2‐ylmethyl)‐1,4,7‐triazaheptane] complex with an intra‐ligand bridging group (–NCH2CH2N–), as well as several solvate molecules (methanol and water). Both MnII cations have similar distorted octahedral coordination geometries. One MnII cation is coordinated by a Cl− anion and five N atoms from the ligand, and the other is coordinated by three Cl− anions and three N atoms of the same ligand. The Mn⋯Mn distance is 7.94 Å. A Cl⋯H—O⋯H—O⋯H—N hydrogen‐bond chain is also observed, connecting the two parts of the complex. |
