Source of material

All reagents and solvents were purchased from commercial sources and used as received without further purification. The ligand N-(pyrazin-2-ylmethyl)pyrazine-2-carboxamide (HL) was prepared by the condensation reaction of dimethyl pyrazine-2-carboxylate (2.75 g, 20 mmol) with 2-aminomethylpyrazine (2.16 g, 20 mmol) under the reflux condition in 30 mL of methanol for 8 h. Followed by rotary evaporation to remove the solvent, a yellow solid was obtained. A solution of Cu(OTf)2 (38.3 mg, 0.106 mmol, OTf = trifluormethansulfonate) in methanol was added to a solution of HL (44.6 mg, 0.206 mmol) in CH2Cl2, affording a green solution. Vapor diffusion of diethyl ether into above filtrate afforded green block-shaped crystals of the title copper complex.

Experimental details

The Uiso values of all hydrogen atoms were set to 1.2Ueq(C). There is a positional disorder of the CH2 and the C=O group in each ligand (not shown in the figure).

Comment

Pyrazine-containing amide ligands have played a very important role in copper coordination chemistry [3, 4] . The crystal structure of pyrazine-pyridine ligands N-(pyridin-2-ylmethyl)-pyrazine-2-carboxamide and N-(pyridin-4-ylmethyl)pyrazine-2-carboxamide and their transition metal chemistry is well developed [5], [6], [7]. A reported mononuclear Co complex with pyrazine-pyrazine imide ligand reveals unusual spin-crossover properties [8]. Here, we synthesized and characterized the structure of a mononuclear copper complex based on a reported pyrazine-pyrazine amide ligand [9].

The amide hydrogen of the educt HL can be deprotonated in presence of the base, allowing the anionic amidate N donor atoms to coordinate to the copper center. In the title compoud, the ligand HL is deprotonated and coordinated via the N3 donor set. Two meridionally coordinated anionic L− ligands are bound to the central copper ion at right angles to one another with an approximately octahedral geometry. The secondary available coordination sites of four spare N atoms from pyrazine and two O atoms from the cabonyl group in the title complex are arranged in a slightly distorted octahedral fashion, which makes this complex useful as a building unit to construct heteronuclear coordination polymers.
