Crystal structure of a second polymorph of tetrakis(pyridin-2-yl)methane
A second polymorph of the title compound, C(21)H(16)N(4), is reported. The original polymorph was solved by our group [Matsumoto et al. (2003 ▶). Tetrahedron Lett. 44, 2861–2864] in the monoclinic space group C2/c and refined to R = 0.050. Now the crystal structure of a tetragonal polymorph (space...
