[(1,2,5,6-η)-Cyclo-octa-1,5-diene](1-ethyl-4-isopropyl-1,2,4-triazol-5-yl-idene)(tri-phenylphos-phane)iridium(I) tetra-fluorido-borate di-chloro-methane sesquisolvate.

The synthesis and crystal structure of a new triazole-based N-heterocyclic carbene iridium(I) cationic complex with a tetra-fluorido-borate counter-anion and solvating di-chloro-methane, [Ir(CH)(CHN)(CHP)]BF·1.5CHCl, is reported. The Ir center of the cationic complex has a distorted square-planar conformation, formed by a bidentate cyclo-octa-1,5-diene (COD) ligand, an N-heterocyclic carbene, and a triphenylphosphane ligand.

1-Ethyl-4-isopropyl-1,2,4-triazolium bromide.

An ionic compound consisting of a triazolium cation and bromide anion, CHN ·Br, has been synthesized and structurally characterized using single-crystal X-ray diffraction and NMR. The compound crystallizes in the monoclinic space group 2/ with the non-hydrogen atoms of one cation lying on general positions and the others lying on a mirror plane. One bromide ion also lies on the mirror.
