Mr. Churchill et al., CRYSTAL AND MOLECULAR-STRUCTURE OF DI(1-PYRAZOLYL)METHANE, CH2(C3N2H3)(2), Journal of chemical crystallography, 26(2), 1996, pp. 93-97
The title compound consists of two planar pyrazolyl fragments oriented
at 73.0 degrees to each other and linked to a common carbon atom. All
hydrogen atoms were located unambiguously and their positions were re
fined.
