3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1) belongs to nitriles. Nitriles are polar, as indicated by high dipole moments. As liquids, they have high relative permittivities, often in the 30s. Asymmetric bioreduction of nitriles is an attractive route to produce optically active nitriles as current metal-catalyzed hydrogenations tend to have low reactivity.Quality Control of 3,3′,3”-Nitrilotripropanenitrile

Trigonal-Bipyramidal Copper(II) Complexes with Symmetric and Unsymmetric Tripodal Tetramine Ligands was written by Dittler-Klingemann, Andreas M.;Hahn, F. Ekkehardt. And the article was included in Inorganic Chemistry in 1996.Quality Control of 3,3′,3”-Nitrilotripropanenitrile This article mentions the following:

The syntheses of the aliphatic tripodal tetramine ligands N(CH2CH2CH2NH2)3 (1), N[(CH2CH2CH2NH2)2(CH2CH2NH2)] (2), and N[(CH2CH2CH2NH2)(CH2CH2NH2)2] (3) are reported. The tripodal N4– ligands 1–3 react with Cu(OH)2 in H2O to give blue Cu(II) complexes. Addition of NH4PF6 to such solutions yields [Cu(N4)(NH3)](PF6)2 [4; N4 = 1, 4a; N4 = 2, 4b; N4 = 3, 4c]. The mol. structures of complexes 4a–c were determined by x-ray diffraction. All three complexes can be crystallized from H2O. Selected crystallog. details are as follows 4a [4b] {4c}: formula C9H27CuF12N5P2 [C8H25CuF12N5P2] {C7H23CuF12N5P2}, M = 558.82 [544.79] MLL {530.76} amu, monoclinic [monoclinic] {orthorhombic}, space group P21/c [C2/c] {P21212}, a = 8.9519(14) [30.181(6)] {15.075(5)} Å, b = 16.803(3) [8.914(3)] {12.2939(14)} Å, c 13.834(2) [14.253(4)] {10.064(2)} , β = 94.183(12) [93.76(2)] {90.0}°, V = 2075.3(10) [3826(3)] {1865.2(12)} Å3, Z = 4 [8] {4}, R = 5.10 [3.42] {4.32}, Rw = 6.67 [5.12] {5.23} for 2480 [2137] {1533} absorption corrected structure factors Fo2 â‰?3σ(Fo2) and 262 [255] {245} refined parameters. The complex dications in 4a–c exhibit a trigonal-bipyramidal geometry with the tertiary N of the tripodal ligand and the NH3 N in the axial positions. Complexes with the unsym. ligands 2 and 3 possess both five and six membered chelate rings. Depending on the ligand, the size of the cavity for the NH3 ligand increases from 4a to 4c. This leads to a shortening of the Cu-NH3 bond length with the shortest bond of this type observed for 4c. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1Quality Control of 3,3′,3”-Nitrilotripropanenitrile).
