Source of material

All the reagents and solvents were used as obtained. The title compound was prepared according to a modified method described by Adams et al. [5] in which the molar amount ratio of raw material iminodiacetic acid (13.3 g, 0.10 mol) and 1,2-diaminobenzene (10.8 g, 0.10 mol) being 1/1. A small amount of MnCl2 ·(H2O)4 (1.0 g, 5.0 mmol) was also added as the catalyst (Yield: 9.40 g, 41.5%). Crystals were obtained two weeks later by slow evaporation of the title compound in ethanol (95%).

Experimental details

H atoms bonded to C atoms were located in difference maps and subsequently treated as riding, with C–H distances of 0.93 Å (aromatic) and 0.97 Å (methylene); Uiso(H) = 1.2Ueq (aromatic and methylene C). H atoms bonded to N and methanol O atoms were also found in difference maps, and refined with restraints of N–H = 0.86(1) Å and O–H = 0.82(1) Å; Uiso(H) values were set equal to 1.2 or 1.5 times of the Ueq of their carrier atoms for N and O atoms, respectively.

Comment

The title compound (BMP) belongs to a new class of bridging ligand containing nitrogen and oxygen donor atoms, which is used in the design and synthesis of very few metal complexes [6]. The mechanism of the synthesis of BMP is still debatable whether it is a byproduct of the synthesis of the bis[N-(benzimidazol-2-ylmethyl)]amine (IDB) or from the IDB ligand decomposition under the catalysis by a metal complex, further producing the semi-condensation product BMP [6]. In this work, we have investigated its formation process by a modified method by using the MnCl2 ·(H2O)4 as the catalyst and the molar ratio of the raw materials iminodiacetic acid and 1,2-diaminobenzene being 1/1. In comparison to the reaction without a catalyst, the product yield of BMP was significantly improved. The colorless crystals can be obtained by a recrystallization of BMP from ethanol solution.

The title compound crystallized in the monoclinic space group P21/c. In its asymmetric unit, there is one half of a BMP and one water molecules with an inversion center residing at the piperazine-2,5-dione centroid. Due to the conjugate effects of the two carbonyl groups, the six-membered piperazine-2,5-dione ring is found to be planar. In comparison with the conformation of a BMP incorporated into a crystal of a metal complex [6], these two benzimidazole groups are also in a trans position to the central piperazine ring, leading to the chair-like conformation. The intermolecular connection between all moieties is furnished by N–H⃛O and O–H⃛O hydrogen bonds. The benzo groups are oriented in a perpendicular arrangement to interact by C–H⃛π interactions.
