Abstract
Molecular and supramolecular structures of two new Mn(II) complexes with tridentate N,N,N-pincer type ligand (L) are presented. [MnL(H2O)2Cl]Cl (1) and [MnL(H2O)3](NO3)2·H2O (2) have octahedral coordination environments with different degrees of distortion. The molecular packing of 1 and 2 is dominated by strong O–H⋯Cl and O–H⋯O H-bonds, respectively, as well as weak C–H⋯O interactions. The percentage of Cl⋯H and O⋯H contacts are 15.5 and 31.5% for 1 and 2, respectively, using Hirshfeld analysis. Based on atoms in molecules theory, the Mn–N, Mn–O, and Mn–Cl bonds have the characteristics of closed shell interactions. Thermal decomposition of L and its Mn(II) complexes are also presented.
