Abstract
The crystal of the title compound, C10H13N2O+.Cl-, consists of 1-benzy l-3-oxo-1H+-pyrazolidinium cations and chloride anions. The five-membe red ring of the cation has an approximate half-chair conformation. Ato m N(1) is sp3 hybridized while atom N(2) is sp2 hybridized. The C(3)-N (2) bond distance of 1.373 (4) angstrom is a partial double bond. Both H atoms connected to N atoms are involved in hydrogen bonding of the N-H ... Cl type.
