Inertia defects of urea
(1986)
By means of an iterative consistency method it has been determined a complete potential field for the urea molecule. The force constants set which interpretates well the vibrational spectra of urea and its deutero derivatives ...
Coordinating properties of some solvents in Cr(CO)5L complexes
(1988)
The influence of the donor-acceptor properties of several solvents on the Cr(CO)5 group in the solid [Cr(CO)5·solvent] complexes has been examined by spectroscopic methods. Relationships were found between the acceptor ...
New complexes [CpFe(dppe)thiophenes]PF6
(Elsevier Ltd, 1996)
The reactions of CpFe(dppe)I with thiophenes in the presence of T1PF6 afforded the new complexes [CpFe(dppe)thiophenes]PF6 (thiophenes = thiophene, 2-methyl-thiophene, 3-methyl-thiophene, 2,5-dimethyl-thiophene, benzothiophene ...
Ionization of the FeX bond in polar solvents: A spectroscopic study of CpFe(dppe)X complexes
(1993)
Electronic absorption spectra for complexes CpFe(dppe)X [with X = Cl, I and CN; dppe = (Ph)2PCH2CH2P(Ph)2; Cp = η5-C5H5] and the cationic derivative [CpFe(dppe)NCCH3]PF6 in different solvents have been measured. The lower ...
Vibrational spectra and normal coordinate analysis of diamminemercury(II) chloride with 14N/15N and H/D isotopic substitution
(1981)
The IR and Raman spectra of solid diamminemercury(II) chloride with 14N/15N and H/D isotopic substitution have been measured. The spectra have been interpreted assuming D3d symmetry for the [Hg(NH3)2]2+ cations which have ...
Ion-pairing and optical activity of diastereomeric zinc(II) 1, 10-phenanthroline, S-valinate systems
(1983)
A series of S-valinatobis(1, 10-phenanthroline)zinc salts in methanolic solution have been prepared and their conductivities and ORD spectra measured. A positive linear correlation of optical rotation with conductance was ...
Sulfur(II)-metal coordination compounds. Group VI metal carbonyl complexes with N,N′-thiobisamines ligands
(1984)
The novel complexes M(CO)5S(NR2)2 (M = Cr, Mo or W) have been prepared by the addition of N,N′-thiobisamine (NR2 = dimethylamine, piperidine, morpholine or dibenzylamine) to UV-irradiated tetrahydrofuran solutions of M(CO)6. ...
Sulphurating and coordinating properties of N,N′-thiobismorpholine towards iron carbonyls
(1990)
The reactions of N,N′-thiobismorpholine, {A figure is presented}, with Fe(CO)5, Fe2(CO)9, Fe3(CO)11 and [(η5-C5H5)Fe(CO)2THF]BF4 were examined. Thiobismorpholine undergoes desulphurization towards Fe(CO)5 with formation ...
Coriolis coupling constants of cis and trans-1,2-dichloroethylene
(1975)
Coriolis coupling constants and the inertia defect for cis- and trans-1,2-dichloroethylene have been calculated, using force constants obtained by the iterative consistency method. The results obtained are compared with ...
