Chemistry is an experimental science, Safety of Tris(2-pyridylmethyl)amine, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 16858-01-8, Name is Tris(2-pyridylmethyl)amine
Crystal structure of a seven-coordinate manganese(II) complex with tris-(pyridin-2-ylmeth-yl)amine (TMPA)
Structural analysis of (acetato-kappa2 O,O?)(methanol-kappaO)[tris-(pyridin-2-ylmeth-yl)amine-kappa 4 N,N?,N??,N???]manganese(II) tetraphenyl-borate, [Mn(C2 H3 O2)(C18 H18 N4)(CH3 OH)](C24 H20 B) or [Mn(TMPA)(Ac)(CH3 OH)]BPh4 [TMPA = tris-(pyridin-2-ylmeth-yl)amine, Ac = acetate, BPh 4 = tetra-phenyl-borate] by single-crystal X-ray diffraction reveals a complex cation with tetra-dentate coordination of the tripodal TMPA ligand, bidentate coordination of the Ac ligand and monodentate coordination of the methanol ligand to a single Mn II center, balanced in charge by the presence of a tetra-phenyl-borate anion. The Mn II complex has a distorted penta-gonal-bipyramidal geometry, in which the central amine nitro-gen and two pyridyl N atoms of the TMPA ligand, and two oxygen atoms of the acetate ligand occupy positions in the penta-gonal plane, while the third pyridyl nitro-gen of TMPA and the oxygen from the methanol ligand occupy the axial positions. Within the complex, the acetate O atoms participate in weak C – H … O hydrogen-bonding inter-actions with neighboring pyridyl moieties. In the crystal, complexes form dimers by pairs of O – H … O hydrogen bonds between the coordinated methanol of one complex and an acetate oxygen of the other, and weak pi-stacking inter-actions between pyridine rings. Separate dimers then undergo additional pi-stacking inter-actions between the pyridine rings of one moiety and either the pyridine or phenyl rings of another moiety that further stabilize the crystal.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Safety of Tris(2-pyridylmethyl)amine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 16858-01-8, in my other articles.
