Cyanoisocyanoacetylene, N≡C−C≡C−N≡C
Angewandte Chemie International Edition, 1998Vacuum pyrolysis of the precursor complex [(CO)5 Cr(CN-CCl=CF-CN)] resulted in the isolation and structure elucidation by molecular spectroscopy of isomer 1. According to ab initio calculations 1 is 109 kJ mol-1 less stable than NC-C≡C-CN, which has been known for some time.

Laser-induced fluorescence of matrix-isolated HCCCCCN+ and HCCCCCCCN+
Chemical Physics Letters, 1995Abstract The cyanodiacetylene (HC5N+) and cyanotriacetylene (HC7N+) cations were produced in a pulsed supersonic discharge through a dilute cyanoacetylene (HC3N) neon mixture, and isolated in solid neon at 5–7 K. The A2Π-X2Π transitions of these cations were investigated by means of laser excitation and Fourier-transform emission spectroscopy.

It is discovered that at low temperatures the characteristic phase separation time constant of solid mixtures ??He in ???He depends on temperature non-monotonically (has a minimum). It means that the velocity of the substance transport slows down at very low temperature and the corresponding values of the effective diffusion coefficient also depend non-
