Crystal structure of trans-bis(diethanolamine-κ3 O,N,O′)manganese(II) bis(3-aminobenzoate)

چکیده
Reaction of m-amino-benzoic acid (MABA), di-ethano-lamine (DEA) and MnCl2·4H2O led to the formation of the title salt, [Mn(C4H11NO2)2](C7H6NO2)2. In the complex cation, the Mn(2+) ion is located on an inversion centre and is coordinated by two symmetry-related tridentate DEA mol-ecules, leading to the formation of a slightly distorted MnN2O4 octa-hedron. The MABA(-) counter-anions are connected to the complex ion by a pair of rather strong O-H⋯O hydrogen bonds, yielding a 1:2 supra-molecular aggregate. Much weaker N-H⋯O hydrogen bonds connect neighbouring aggregates into a three-dimensional network structure.

In the title compound, [Mn(NCS)(2)(C(13)H(19)N(3)O)(H(2)O)], the Schiff base acts as an N,N',N"-tridentate ligand, forming two five-membered chelating rings with the Mn(II) atom. The distorted octa-hedral geometry around the metal atom is completed by two cis-positioned N-bound thio-cyanate ligands and one water mol-ecule. In the crystal, adjacent mol-ecules are linked through O-H⋯O, O-H⋯S and ...
