Abstract:	The crystal and molecular structures of 2-Hydroxy-1-naphthalenecarboxaldehyde (I) and 3-Hydroxy-2-naphthalenecarboxaldehyde (II) were determined. Compound (I) crystallizes in the space groupP2₁/n witha+5.589(2),b+9.352(2), andc+15.490(3) Å, =98.14(3)°, andZ+4. Compound (II) crystallizes inP2₁/n witha+16.831(11),b+5.936(3), andc+8.295(3) Å =97.24(5)°. andZ+4. The structures were solved by direct methods, and refined by fullmatrix least squares toR+0.071 andR_w+0.083 forI, andR+0.047 andR_w+0.061 forII.
