CN- ligands

Further similarity with Mn may be seen in the fact that the vast majority of the compounds of Fe are high-spin. Only ligands such as bipy and phen (already mentioned) and CN , which are high in the spectrochemical series, can induce spin-pairing. The low-spin [Fe(CN)g] , which is best known as its red, crystalline potassium salt, is usually prepared by oxidation of [Fe(CN)6]" with, for instance, CI2. It should be noted that in [Fe(CN)6] the CN ligands are sufficiently labile to render it poisonous, in apparent contrast to [Fe(CN)6]" , which is kinetically more inert. Dilute acids produce [Fe(CN)5(H20)] , and other pentacyano complexes are known. [Pg.1090]

Similar structural features are present in the [FeFe]-hydrogenases (FeS electron relay centers, CO and CN-ligands at the active site, and channels for gas access). [Pg.615]

It is further noteworthy that K4[Ru(CN)6] 3H2O shows an isomer shift close to the shifts of Ru(lV) compounds, from which it is inferred that practically two t2g electrons have been delocalized from the Ru(II) cluster to the strong 7t-bonding CN ligands [123]. [Pg.274]

K2Hg(CN)4 and the crown ether dibenzo-18-crown-6 in aqueous ethanol yield the crystalline [K(C2oH2406)]2[I Ig(CN)4]-2I I2C) the structure contains two independent potassium-crown complexes and a distorted tetrahedral Hg(CN)4 entity (rav(l Ig—C) 218.4, rav(C—N) 112.3 pm) which coordinates to one of the complexed K ions through one of the CN ligands (slight lengthening of the C—N bond).116... [Pg.1261]

Co3+ when bonded to five CN ligands that are soft, has become soft as a result of the symbiotic effect. Ligands with the ability to bond by using different donor atoms are known as ambidentate ligands. [Pg.583]

Substitution of the coordinated aqua trans to the nitrido (N3 ) ligand in complexes of the form [ReN(H20)(CN)4]2 with CN ligands in the equatorial cis plane, denoted by ReNCfROjCN. [Pg.116]

NMR data indicate a structure for the latter having a direct Pt-Pt bond with a terminal hydride bound to one Pt and the CH CN ligand to the other. [Pg.344]
