Uses

N-Butyldiethanolamine (H2bdea, N-n-butyldiethanolamine) has been used in the synthesis of the following complexes (Hdnba = 3,5-dinitrobenzoic acid, Hpta = p-toluic acid, H2tpa = terephthalic acid):new mononuclear [Cu(Hbdea)2]·2Hdnba , dinuclear [Cu2(μ-Hbdea)2(N3)2] and [Cu2(μ-Hbdea)2(pta)2]·2H2O1D polymeric [Cu2(μ-Hbdea)2(μ-tpa)]n·2nH2O copper(II) compoundstetranuclear 3d-4f single-molecule magnet (SMM) complexes

General Description

N-Butyldiethanolamine (N-n-butyldiethanolamine) is a tertiary amine. It acts as an N-substituted diethanolamine ligand. It reacts with chromium(II) and lanthanide(III)/rare earth salts (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y) in the presence of coligands to afford three series of isostructural 1:1 3d(Cr(III))/4f(Ln(III)) coordination cluster compounds.

Flammability and Explosibility

Nonflammable

Safety Profile

Mddly toxic via ingestion. A skin and severe eye irritant. Combustible when exposed to heat or flame. To fight fire, use alcohol foam, foam, CO2, dry chemical. Incompatible with oxidizing materials. When heated to decomposition it emits toxic fumes of NOx. See also AMINES.

Synthesis and characterization of rhenium(III) complexes with (Ph2PCH2CH2)2NR diphosphinoamine ligands

The synthesis and characterization of a new series of neutral, six-coordinated compounds [ReIIIX3(PNPR)], where X is Cl or Br and PNPR is a diphosphinoamine having the general formula (Ph2PCH2CH2)2NR (R = H, CH3, CH2CH3, CH2CH2CH3, CH2CH2CH2CH3 and CH2CH2OCH3) are reported. Stable [ReIIIX3(PNPR)] complexes were synthesized, in variable yields, starting from precursors where the metal was in different oxidation states (iii and v), by ligand-exchange and/or redox-substitution reactions. The compounds were characterized by elemental analysis, proton NMR spectroscopy, cyclic voltammetry, UV/vis spectroscopy, positive-ion electrospray ionization mass spectrometry (ESI(+)-MS) and X-ray diffraction analysis. Although the formulation of the complexes allows either meridional or facial isomers, the latter arrangement was prevalent both in the solid and solution states. Only [ReCl3(PNPH)] showed a meridional configuration both in solution and in the crystalline state. [ReBr3(PNPme)] prefers the meridional configuration in the crystalline state and the facial one in solution. While ESI(+)-MS and voltammetric data seem to indicate some dependency from the nature of the alkyl substituent at the nitrogen, the available structural data of the complexes show only slight differences both for angles and bond lengths upon change of the alkyl chain tethered to the nitrogen.
