The reactions of pyrazole based ligands with Co(II) salts in the presence of NaN3 or NH4NCS afforded the cationic-anionic complexes [Co(bdmpzpy)2][Co(N3)4] (1) and [Co(bdmpzpy)2][Co(NCS)4]·2CH3NO2 (2) contg. tetrathiocyanato- and tetraazido-Co(II) complex anions as well as the mononuclear complexes [Co(bepza)(NCS)2] (3), [Co(tedmpza)(NCS)]ClO4·0.5H2O (4) and [Co(tedmpza)(N3)]ClO4·H2O (5) where bdmpzpy = 2,6-bis[(3,5-dimethyl-pyrazol-1H-yl)-methyl]pyridine, bepza = bis(pyrazol-1H-ylethyl)amine and tedmpza = tris(3,5-dimethyl-pyrazol-1H-ylethyl)amine. The complexes were structurally characterized by elemental microanalyses, IR and UV-visible spectroscopy and by single crystal x-ray crystallog. [on SciFinder(R)]
