37366-09-9. Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer,introducing its new discovery.
[(eta6-C6H6)RuII(L)(Cl/N3/CN/CH3CN)]+/2+ complexes of non-planar pyrazolylmethylpyridine ligands: Formation of helices due to C-H?X (X?=?Cl, N) interaction
Structural analysis of a previously reported half-sandwich complex having three-legged “piano-stool” geometry [(eta6-C6H6)RuII(L1)Cl][PF6] (1) (L1?=?2-(pyrazol-1-ylmethyl)pyridine) is described. Treatment of 1 with (i) Ag(CF3SO3) in CH3CN and (ii) NaN3 in CH3OH, and (iii) the reaction between [(eta6-C6H6)Ru(L2)Cl]-[PF6]?(2) (previously reported) and NaCN in C2H5OH led to the isolation of [(eta6-C6H6)Ru(L1)(CH3CN)][PF6]2 (3), [(eta6-C6H6)Ru(L1)(N3)][PF6] (4), and [(eta6-C6H6)Ru(L2)(CN)][PF6] (5), respectively (L2?=?2-(3,5-dimethyl-pyrazol-1-ylmethyl)pyridine). The complex [(eta6-C6H6)Ru(L4)Cl][PF6] (6) with a new ligand (L4?=?2-[3-(4-fluorophenyl)pyrazol-1-ylmethyl]pyridine) has also been synthesized. The structures of 3-6 have been elucidated (1H NMR spectra; CD3CN). The molecular structures of 1, 4, and 6¡¤C6H5CH3 have been determined. Notably, the crystal-packing in these structures is governed by C-H?X (X?=?Cl, N) interactions, generating helical architectures.
