The entire mol-ecule exhibits point group symmetry 4/m. In the asymmetric unit, except for two C atoms of the phenyl ring, all other atoms lie on special positions. The Mg(II) atom is situated at a site with symmetry 4/m, while the N and the C atoms of the porphyrin macrocycle, as well as two C atoms of the phenyl ring and the Br atom lie in the mirror plane containing the porphyrin core. The H atoms of the axially bonded water mol-ecule are incompatible with the fourfold rotation axis and are disordered over two sites. In the crystal, mol-ecules are packed in rows along [001]. Weak inter-molecular C-H⋯π and C-H⋯Br inter-actions, as well as O-H⋯Br hydrogen bonds, stabilize the crystal packing. %G English %L hal-01141467 %U https://univ-rennes.hal.science/hal-01141467 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ SCR_ICMV %~ SCR-CD %~ STATS-UR1 %~ UR1-SPM %~ ISCR-PRATS %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ ISCR-CORINT %~ UR1-SDLM %~ UR1-SDLMJONCH %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ ISCR-CORINT1 %~ UR1-MMS %~ TEST2-HALCNRS
