¿Será el pirazol un cangrejito, con sus dos pinzas?

Pues un poco sí: un nitrógeno forma un #tetrelbond con el carbono; el otro interacciona con el oxígeno a través de un #hydrogenbond

Rotational spectrum and theoretical calculations of pyrazole⋯CO2 complex: Tetrel and hydrogen bond interactions The complex between pyrazole and carbon dioxide has been generated in a supersonic jet and characterized using Fourier transform microwave spectroscopy and stat

A greenhouse gas molecule such as CO₂ is small and elusive... few CO₂ complexes with heterocycles are known experimentally!
