Abstract

In the title compound, 2C(10)H(15)N(4)Se(+)·Cl(-)·OH(-), a singly protonated mol-ecule of the organic selenide participates in hydrogen bonding with neighboring mol-ecules, forming zigzag chains along [001]. The molecule adapts a cis bridging mode with a C-Se-C angle of 102.13 (15)°. π-π stacking inter-actions are observed between the closest pyrazole rings of neighboring chains [centroid-centroid distance = 3.888 (1) Å] and hydrogen bonding occurs through bridging chloride anions and hydroxide groups. Additionally, O-H⋯Cl hydrogen bonds are formed.
