1-Phenylazo-2-Naphthylamihe Complex Compounds. II: Normal Coordinate Analysis of the bis(1-Phenylazo-2-Naphthylaminato)Nickel(II) Complex

Abstract

A normal coordinate analysis was carried out for bis(1-phenylazo-2-naphthylaininato)nickel (II). Two simplified models were employed, (a) a 41-particle model (“whole molecule”), where the CH atoms were considered as point masses, and (b) a fragment of 32 atoms (“half molecule”) with the hydrogens included. The calculated vibrational frequencies are correlated with observed data. The potential energy distribution was used for approximate descriptions of the normal modes.

Key Words:

• Vibrational frequencies
• Force constants
• Bis(1-phenylazo-2-naphthylaminato)nickel(II)
• Ni(C₆H₅N)₂(N₂C₁₀H₂)₂
