Source of material
2,6-Pyridinedicarboxylic acid dihydrazide (1.95 g, 0.010 mol) was added to a dry methanolic solution (50 mL) of the methyl ester of iminopyrazine-2-carboxylic acid (2.6 g, 0.025 mol), prepared in situ from 2-cyanopyrazine and sodium metal (stirred at room temperature for 12 h) and the mixture refluxed for 24 h with the formation of a yellow powder. The solid was filtered off washed with water, methanol and ether and dried under vacuum. Yield (6.5 g, 80%).
Experimental details
The C-bound H atoms were geometrically placed (C—H = 0.95–0.98 Å) and refined as riding with Uiso(H) = 1.2–1.5 Ueq(C) and with Uiso(H) set to 1.2 Ueq(N) [1], [2], [3].
Discussion
The extended “polytopic” ligands 2pzoap (N′2,N′6-bis(1-(pyrazin-2-yl)ethylidene)pyridine-2,6-dicarbohydrazide) contain multiple, contiguous coordination pockets, and in principle there are many different ways in which they could bind metal ions. The complexes containing the ligand 2pzoap have been reported. But the structure of the ligand/educt 2pzoap has not been reported [4], [5], [6], [7]. As shown in the figure, the compound 1 crystallizes in the monoclinic space group P2/n with the title molecule located on a twofold axis and a methanol molecule in general position. The bond lengths of N3 = C5, N2—C4 and C3—N1 are 1.281, 1.344 and 1.338 Å, respectively, which are similar with the reference [8].
