Abstract
trans-Dibromobis(5-tert-butylpyrazole-N-2)copper(II), trans[CuBr2 (Hpz(tBu) )(2)] (Hpz(tBu) is 5-tert-butylpyrazole, C7H12N2), exhibits a distorted squ are-planar geometry with a significant tetrahedral twist, while trans-dibro motetrakis(5-tert-butylpyrazole-N-2)copper(II), trans-[CuBr2(Hpz(tBu))(4)], adopts a distorted octahedral geometry across a crystallographic inversion centre. Both compounds exhibit intramolecular N-H . . . Br hydrogen-bondin g interactions.
