摘要

The title complex salt, (C16H36N)[MnBr(C32H16N8)] or (TBA)[MnIIBr(Pc)] (TBA is tetrabutylammonium and Pc is phthalocyaninate), has been obtained as single crystals by the diffusion technique and its crystal structure was determined using X-ray diffraction. The high-spin (S = ) [MnIIBr(Pc)]? macrocycle has a concave conformation, with an average equatorial Mn—N(Pc) bond length of 2.1187?(19)??, an axial Mn—Br bond length of 2.5493?(7)?? and with the MnII cation displaced out of the 24-atom Pc plane by 0.894?(2)??. The geometry of the MnIIN4 fragment in [MnIIBr(Pc)]? is similar to that of the high-spin (S = ) manganese(II) tetraphenylporphyrin (TPP) in [MnII(1-MeIm)(TPP)] (1-MeIm is 1-methylimidazole).
