Other conformational functions are located becoming similar into the two mol-ecules. The various positioning of this OH group results in various hydrogen-bonding systems when you look at the crystal frameworks of (we) and (II). Whereas in (I) inter-molecular O-H⋯O hydrogen bonds using the pyridazinone carbonyl O atom as acceptor generate stores with a C(7) theme expanding parallel to your b-axis path, into the crystal of (II) pairs of inversion-related O-H⋯O hydrogen bonds with
