Crystal structure and Hirshfeld surface analysis of 6-imino-8-(4-methyl-phen-yl)-1,3,4,6-tetra-hydro-2 H-pyrido[1,2- a]pyrimidine-7,9-dicarbo-nitrile
{{output}}
In the ten-membered 1,3,4,6-tetra-hydro-2H-pyrido[1,2-a]pyrimidine ring system of the title compound, C17H15N5, the 1,2-di-hydro-pyridine ring is essentially planar (r.m.s. deviation = 0.001 Å), while the 1,3-diazinane ring has a distorted twist-boat conforma... ...
