“…Ruthenium nitrosyl structures generally show a nearly linear Ru-N-O bond angle. 41,56,57,77,[79][80][81][82][83] In I (Table 3), the Ru-N-O bond angle of 167.7°is slightly smaller than those of some other ruthenium nitrosyl complexes, which ranges from 180 to 170.4(5). 41,83 Besides the slight bond angle O(5)-N(5)-Ru bending in I, the interatomic distance observed of 1.739(2) Å is in the range of those observed for other ruthenium nitrosil ammines which ranges from 1.715(5) to 1.81 Å.…”

The complex fac-[Ru(NO)Cl2(kappa(3)N(4),N(8),N(11)(1-carboxypropyl)cyclam)]Cl.H2O (1-carboxypropyl)cyclam=3-(1,4,8,11-tetraazacyclotetradecan-1-yl)propionic acid) was prepared in a one pot reaction by mixing equimolar amounts of RuNOCl 3 and (1-carboxypropyl)cyclam and was characterized by X-ray crystallography, electrospray ionization tandem mass spectrometry (ESI-MS/MS), elemental analysis, NMR, and electronic and vibrational (IR) spectroscopies. fac-[Ru(NO)Cl 2(kappa(3)N(4),N(8),N(11)(1-carboxypropyl)cyclam)]Cl.H2O crystallizes in the triclinic, space group P1, No. 2, with unit cell parameters of a=8.501(1) A, b=9.157(1) A, c=14.200(1) A, alpha=72.564(5) degrees , beta=82.512(5) degrees , gamma=80.308(5) degrees , and Z=2. The Ru-N interatomic distance and bond angle in the [Ru-NO] unit are 1.739(2) A and 167.7(2) degrees , respectively. ESI-MS/MS shows characteristic dissociation chemistry that initiates by HCl or NO loss. The IR spectrum displays a nu(NO) at 1881 cm(-1) indicating a nitrosonium character. The electronic spectrum shows absorptions bands at 264 nm (log epsilon=3.27), 404 nm (log epsilon=2.53), and 532 nm (log epsilon=1.88). (1)H and (13)C NMR are in agreement with the proposed molecular structure, which shows a very singular architecture where the cyclam ring N (with the carboxypropyl pendant arm) is not coordinated to the ruthenium resulting in a kappa(3) instead of the expected kappa(4) denticity.

“…99 . 100 [Ru(pyS) 2 (NO)(dppm-O-P)]PF 6 is formed from fac-[RuCl 3 (NO)(dppm)], one P of the phosphine being displaced and oxidized to dppmO. 101 Successive conversion of [Ru(bipy)(tpm)Cl] + via aqua and nitro complexes leads to [Ru(bipy)(tpm)NO](ClO 4 ) 3 , a linear {RuNO} 6 species, which can be reduced to the [Ru(bipy)(tpm)NO] 2+ ion.…”

The aryl [Li(thf) 4 ][Fe(C 6 Cl 5 ) 4 ] is notable, as is the nitride [Fe(N)(Me 3cyclam-OAc)] 2+ , the first Fe VI compound apart from the ferrate ion. Interest continues in Fe nitrosyl, oxo-and imide species; there is compelling work on three-and four-coordinate iron. In the case of ruthenium, interest continues in olefin metathesis and complexes of ligands such as bipy, phen and terpy, on account of their photochemical properties.
