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

The synthesis of a new bis-tripodal ligand N,N,N′,N′-tetrakis[(1,5-dimethylpyrazol-3-yl)methyl]-1,4-phenylenediamine is reported and clearly established from its spectroscopic data (IR, 1 H 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 [C 30 H 40 N 10 ; 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].
