The crystal structure of the alkaline earth metal hydrogen phthalate was determined. Ca (C8H5O4) · 2H2O is orthorhombic and belongs to the space group Pmn21 (No.31) with unit cell parameters of a = 2.7482, b = 0,9125, c = 0.6926nm, Z = 4; C8H5O4) 2 · 2H2O are orthorhombic (space group No.36) with unit cell parameters of a = 2.8465, b = 0.8798, c = 0.6980nm and Z = 2 · H2O is a monoclinic system belonging to (No.7) space group with unit cell parameters of a = 3.1051, b = 0.7008, c = 1.1781 nm, β = 100.55 °, Z = 6 . The infrared and Raman spectra of these compounds were investigated. The coordination structure between ortho-formate and alkaline earth metal ions in solid samples and their influence on the spectra were discussed.
