 Title    Structural Influence of Hydrogen Bonding and ^r-Stacking in fra/is-Diazido-tetra- kis(pyrazole)nickel(II) and rra/is-Diazido-tetrakis(3-methylpyrazoIe)nickel(II)  
 Abstract    The molecular nickel complexes fra«s-diazido-tetrakis(pyrazole)nickel(II) and trans-dia-zido-tetrakis(3-methylpyrazole)nickel(II) feature terminal monohapto-bound azide ligands. The pyrazole (pyr) ring planes are aligned along the Nazide-Ni-Nazide axis by intramolecular N-H—Nazide bonds. The crystal packing is controlled by jr-stacking between both pyrazole rings and azide ligands, N -H —Nazide hydrogen bonds, and intermolecular N-H—jrpyr and C-H —N/jrazide interactions.
