The unique properties of pyrazole raised the interest of preparing a corrole containing one such moiety on its C 10 position. Its single‐crystal X‐ray structure uncovers it to be a dimer wherein the two monomeric units are held together by very strong corrole‐pyrazole NH ··· N hydrogen bonding interactions that lead to a very well self‐assembled network. The corresponding gallium(III) complex is isolated as a trimer in which all hydrogen bonding interactions are between the pyrazole subunits. In contrast, a tetrameric coordination complex is formed from the gallium(III) complex of a corrole with a pyridyl moiety on C 10 .
