Dipole rotation in some substituted ferrocenes

Autor: Leonidas Phillips, Stephen W. Filipczuk

Publikováno v: Journal of Molecular Liquids. 59:13-25

The dielectric relaxation times (τ′) of dilute cyclohexane and benzene solutions of several mono-, di- and penta-substituted ferrocenes are determined. From these we derive the corresponding relaxation times (τ) for intra- and overall molecular d

A solution-state dipole moment and microwave dielectric loss study of Ti, Zr, Hf and Sn cyclopentadienyl compounds

Autor: Gregory W. Allen, Leonidas Phillips, Stephen W. Filipczuk, Manuel J. Aroney

Publikováno v: Journal of Molecular Liquids. 54:147-154

Dielectric properties of cyclopentadienyl complexes Cp2MX2 and Cp4M (M = Ti, Zr, Hf or Sn; X = Cl or Br; Cp = cyclopentadienyl) have been investigated in dilute benzene or 1,4-dioxane solution using the standard refractivity and microwave dielectric

Electric dipole moments and charge redistribution in some substituted ferrocenes

Autor: Stephen W. Filipczuk, Leonidas Phillip

Publikováno v: Journal of Molecular Liquids. 47:261-270

The dipole moments of some mono- , di- and penta-substituted ferrocenes as solutes in cyclohexane have been determined by a standard microwave dielectric loss technique [1]. Ligand group moments for the monosubstituted ferrocenes are derived. One of

Publikováno v: J. Chem. Soc., Dalton Trans.. :1409-1415

Dipole moments have been determined for iron(III), cobalt(III), nickel(II), palladium(II), platinum(II) and copper(II) complexes of the mercapto-β-diketones RC(SH):CH·C(O)R′[R = Me or Ph, R′= Ph; R = Me, C4H3S (2-thienyl), Ph. p-MeC6H4, or p-Br

Dipole-moment measurements on metal chelate complexes. Part III. Dipole-moment and dielectric-relaxation measurements on some tetrahedral zinc(II) complexes of seven mercapto-β-diketones

Autor: Manoranjan Das, Stanley E. Livingstone, John W. Hayes, Donald V. Radford, Stephen W. Filipczuk

Publikováno v: J. Chem. Soc., Dalton Trans.. :886-888

Dipole moments and relaxation times have been determined for tetrahedral zinc(II) complexes of the mercapto-β-diketones RC(SH):CH·C(O)R′[R = Me or Ph, R′= Ph; R = Me, C4H3S (2-thienyl), Ph, p-MeC6H4, or p-BrC6H4, R′= CF3] from both static-pol
