Observations on the i.r. intensity criterion for the bonding mode in thiocyanate complexes

Oxidative Addition Reactions of P(CN)3, P(NCO)3 and P(NCS)3 to (η5-C5Me5)Co(CO)2

“…In the cyanate complex the vibrational frequencies v(CN), v(CO) and (3(NCO) indicate that the coordi nation to metal is via the N atom [7], For the thio cyanate complex the determination of the internal standard ratio of y(CN) of the SCN band by the Bailey mehtod [8 ] indicates that the coordination is also via the N atom.…”

Studies on the Effect of Various Anions and Diphenyl Sulfoxide on the Stereochemistry of Lanthanide(III) Coordination Compounds of 4[N-(2′-hydroxy-1′-naphthalidene)amino] Antipyrinesemicarbazone

“…Consequently, N-bonding is expected with the hard (class-A) metal ions, while S-bonding should take place with those of the soft [50]. Bailey et al [51] suggested that the region near or above 2100 cm )1 for S-bonding, and below this for N-bonding. The CS stretching frequency (m 1 ) was assigned in the following regions 860-780 cm )1 for MANCS and 720-690 cm )1 for MASCN group [51].…”

The NACAS frequency (m 3 ) is also different for the two isomers 490-450 cm )1 for MANCS and 440-400 cm )1 for the MASCN group [51].…”

Critical survey of stability constants of complexes of thiocyanate ion (Technical Report)

“…With some metals the thiocyanate ion can also serve as a bridging ligand, forming either isopoly or heteropoly complexes (68B). Experimental evidence for the mode of bonding comes primarily from infrared data (60M,62Tr,65F0,65K,66C1,67S,71As,71B) or other measurements (64T, 69Br, 74B, 822). Stability constant values and other thermodynamic constants for metal thiocyanate complexes appear in the early compilations of such data (64S, 69Pe, 71S, 77Sm, 82H).…”
