Synthesis, characterization, and structural studies of two heteroleptic Mn(II) complexes with tridentate N,N,N-pincer type ligand

摘要

Molecular and supramolecular structures of two new Mn(II) complexes with tridentate N,N,N-pincer type ligand (L) are presented. [MnL(H2O)(2)Cl]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-HCl and O-HO H-bonds, respectively, as well as weak C-HO interactions. The percentage of ClH and OH 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.
