“…(1E,2E)-2,2 -Dipyridylglyoxime (1) was synthesized by the method of Richardson and coworkers [16], which, in contrast to previously reported procedures [12][13][14][15], gives a single isomer of the compound. The synthesis protocol (Scheme 2) involves the reaction of 2,2 -pyridyl with hydroxylammonium chloride in the presence of an excess of sodium hydroxide.…”

1E,2E)-2,2 -dipyridylglyoxime (1) was synthesized by a literature method involving the reaction of 2,2 -pyridyl with an excess of hydroxylammonium chloride and sodium hydroxide in distilled water. 1 was characterized by elemental analysis, melting point, mass spectrometry, and NMR ( 1 H and 13 C) spectroscopy. In addition, the crystal structure of 1 was determined by low temperature X-ray analysis. 1 crystallizes in the monoclinic space group P2 1 /n with four formula units in the unit cell and the following unit cell parameters: a = 6.269(1)Å, b = 10.258(1) A, c = 9.132(1)Å, β = 107.59(1) • , and V = 559.7(1) A 3 . Strong O· · ·N hydrogen bonds link the molecules of 1, forming three-dimensional hydrogen-bonded networks; whereas the unclassical C· · ·O hydrogen bonds result in the formation of C1,1(9) and C2,2(18) infinite chains and dimmer pairs with the graph-set descriptor R2,2(16). Lastly, the structure of 1 was fully optimized using DFT calculations p)) and the NBO and Mulliken charges were calculated at the same level of theory. C 2011 Wiley Periodicals, Inc.

“…In particular, dipyridil glyoxal dioximes (I, Scheme 1) where R = pyridine, have been used as analytical reagents and for the spectrophotometric determination of Pd II ions [12,13]. Note that oximes can exist both in the E-and Z-form [13].…”
