N,N'-Dineopentyl-naphthalene-1,8-diamine.


ABSTRACT: In the title compound, C(20)H(30)N(2), all bond distances and angles fall within the usual ranges but the C(ipso)-N distances [1.391?(5) and 1.398?(4)?Å] are slightly shorter than the corresponding typical average distance of 1.42?(3)?Å. The N atoms may be described as pyramidal sp(3)-hybridized with an N-H?H-N separation of 2.07?(2)?Å. This is necessitated because the two C(bridgehead)-C(ipso)-N-C torsion angles [170.6?(4) and 172.6?(3)°] would require the amine H atoms to be in prohibitively close proximity if the N atoms were assumed to be sp(2)-hybridized.

In the title compound, C(20)H(30)N(2), all bond distances and angles fall within the usual ranges but the C(ipso)-N distances [1.391 (5) and 1.398 (4) Å] are slightly shorter than the corresponding typical average distance of 1.42 (3) Å. The N atoms may be described as pyramidal sp(3)-hybridized with an N-H⋯H-N separation of 2.07 (2) Å. This is necessitated because the two C(bridgehead)-C(ipso)-N-C torsion angles [170.6 (4) and 172.6 (3)°] would require the amine H atoms to be in prohibitively c  ...[more]
