The Uses of 2,2'-(Butylimino)diethanol

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]·2H₂O
1D polymeric [Cu₂(μ-Hbdea)₂(μ-tpa)]_n·2nH₂O copper(II) compounds
tetranuclear 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

Non flammable

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.
