Abstract

Mn(II) coordination compounds with tripodal N,N,N-tris-(2-benzimidazolylmethyl)amine (TMBA) have been synthesized and spectro-scopically characterized. The crystal structure of [Mn(TMBA) (NO₃) (CH₃OH)] (NO₃) H₂O has been determined. The compound crystallizes in the monoclinic space group P2₁/c with four formula units in a cell of dimensions a = 11.3825(2), b = 13.4338(2), c = 17.9548(3) Å, β = 100.026(1)°; final R = 0.0299, based on 4745 independent reflections. The structure indicates the complex ion has a heptacoordinate metal center with a coordination polyhedron best described as a capped octahedron. The octahedron is defined by three nitrogen atoms from the benzimidazole moieties (N(1A), N(1C) and N(1B)), the oxygen atom of the methanol O(41), and two oxygen atoms from the coordinating nitrate group O(11) and O(12). The capping ligating atom is the bridging N(1) from the TMBA ligand with a longer Mn-N distance of 2.551(1) Å.
