摘要：

The X-ray crystal structure of the title compound shows it to be the enol tautomer and with two molecules in the unit cell, with hydrogen bond lengths, R(O··O), of 2.446 and 2.474 Å. These and other hydrogen bond parameters (δ, Δδ(H-D) and νOHO) of similar compounds are compared and attempts made to relate them to Q, which is derived from the bond asymmetry of the enol ring. © 1990.
