Complexes of cobalt(II) and nickel(II) with the ligands 2- acetamidopyridine (acpy) and 2-aminomethyl-6-methylpyridine (mepic) have been prepared and studied. They included [Co(acpy)2X2], [Co(mepic)2X2], [Ni(acpy)2X2], and [Ni-(mepic)2X2], in which X is Cl, Br, I, or NCS; [Co(acpy)2(NO3)2], [Co(mepic)2(NO3)2], [Ni(acpy)2(NO3)2], [Ni(mepic)3NO3]NO3, [Co(acpy)3](ClO4)2, [Co(mepic)3](ClO4)2, [Co(mepic)3](CoCl4), [Ni(acpy)2(H2O)2](ClO4)2, and [Ni(mepic)2(H2O)2](ClO4)2. The inner complex of 2-methylpyridine-6- carboxylic acid [Co(mepiac)2,2H2O)] was also isolated. In all cases, the magnetic properties, conductances, reflectance spectra, absorption spectra, and infrared spectra are in agreement with the concept that they are spin-free, six-coordinate octahedral complexes. The substance [Ni(mepic)2NO3]NO3 contains both bidentate and ionic nitrate.

Homonuclear Decoupling

The iridoid glucoside theveside has been isolated from the leaves and stems of three taxa of Lantana camara (Verbenaceae), where it occurs as the sodium salt. Elucidation of the structure was primarily from 1H and 13C n.m.r. spectra. The stereochemistry of the molecule was established from 1H homonuclear decoupling and Overhauser enhancement experiments. Theveside may now be fully described by the systematic name [1S- (1α,4aα,7aα)]-1-(β-D-glucosyloxy)-4a-hydroxy-7-(hydroxy-methyl)- 1,4a,5,7a-tetrahydrocyclopenta[c]pyran-4-carboxylic acid. Theveside, already found in two members of the Apocynaceae, is previously unreported in the Verbenaceae.

Methyl Pyridine

Complexes of copper(II) with 2-acetamidopyridine (acpy) and with 2- methyl-pyridine-6-carboxylic acid (mepiac-H) have been prepared. The compounds studied included [Cu(acpy)2Cl2], [Cu(acpy)2Br2], [Cu(acpy)2(NCS)2], [Cu(acpy)2(NO3)2], [Cu(acpy)2(H2O)ClO4]ClO4,H2O, [Cu(mepiac)(mepiac-H)Cl], [Cu(mepiac)(mepiac-H)-Br], [Cu(mepiac)(mepiac-H)BrH2O], and [Cu(mepiac)2H2O]. The magnetic properties, conductances, reflectance and solution spectra, as well as infrared spectra, are in agreement with the copper(II) complexes of acpy being six-coordinate and those of mepiac-H having a five- coordinate structure.
