ligands in (imSQR)2MnX complexes (R = Me, X = Cl (1), Br (2), I (3), N3 (4), NCO (5); R = OMe, X =Br (7), I (8), N3 (9); R = CF3, X = Cl (10), Br (11), I (12), N3 (13), NCO (14)). Molecular structures of 2, 9–11 have been established by single-crystal X-ray analysis. The increasing of the sterical bulkiness of imSQR ligands leads to the significant distortion of coordination polyhedrons from the almost ideal
