Thus, 2-hydrazinopyridine was treated with CS2 in CHCl3 to give triazolopyridinethiol II, which was heated with ClCH2CN and Et3N in PhMe to give I (Z = N). .

Crystal structures and magnetic properties of dinuclear copper(II) complexes of 2,6-bis(N-(2-pyridylmethyl)formimidoyl)-4-methylphenolate with azido and cyanato-0 exogenous ligands

Crystal structures and magnetic properties of dinuclear copper(II) complexes of 2,6-bis(N-(2-pyridylmethyl)formimidoyl)-4-methylphenolate with azido and cyanato-0 exogenous ligands. Mallah, Talal; Kahn, Olivier; Gouteron, Jacqueline; Jeannin, Suzanne; Jeannin, Yves; O'Connor, Charles J. (Lab. Spectrochim. Elements, Univ. Paris-Sud, Orsay 91405, Fr.). Inorg. Chem., 26(9), 1375-80 (English) 1987. CODEN: INOCAJ. ISSN: 0020-1669. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 75, 77 [Cu2(Famp)X](ClO4)2 (I; HFamp = 2,6-(RCH2N:CH)2-4-CH3C6H2OH, R = 2-pyridyl; X = 1,1-N3, 1,1-OCN) were prepd. The crystal structures of I (X = N3, NCO) are isomorphous: space group P21, with a 8.973(3) and 8.987(3), b 14.785(3) and 14.774(4), c 9.650(1) and 9.664(1) ?, b 90.63(2) and 90.71(2)°, resp., and Z = 2. The Cu(II) ions of the binuclear units are bridged by the phenolic O atom and by the X exogenous ligand. 107556-66-1 and 3731-51-9 which are cas registry numbers of chemicals are mentioned. Both N3 and OCN bridge in an end-on fashion and make angles of 18.7(8) and 18.8(8)°, resp., with the plane of the Famp ligand. OCN bridges by its O atom. The magnetic and EPR properties were studied: in I (X = N3), the Cu(II) ions are antiferromagnetically coupled with a singlet-triplet (S-T) energy gap of -161 cm-1; in contrast, I (X = NCO) is 1 of the few Cu(II) dinuclear complexes with a triplet ground state. The S-T energy gap is 43 (10) cm-1. .
