Synthesis, characterisation and crystal structure of a new bis-tripodal ligand: N,N,N′,N′-tetrakis[(1,5-dimethylpyrazol-3-yl)methyl]-1,4- phenylenediamine

Abstract

The synthesis of a new bis-tripodal ligand N,N,N′,N′- tetrakis[(1,5-dimethylpyrazol-3-yl)methyl]-1,4-phenylenediamme is reported and clearly established from its spectroscopic data (IR, 1H NMR, mass spectrometry) and elemental analysis. The X-ray structure of the target compound has been determined and the pyrazolyl ligand crystallises in the space group P-1 [C30H40N10; a = 7.1533(7)Å; b = 9.7541(10)Å; c = 10.7169(10)Å; α = 94.420(8)°; β = 97.920(8)°; γ = 108.088(9)°, Z =2].
