Bis(1,10-phenanthroline)lithium perchlorate: Crystal structure and dissociation in acetone

The composition of the solid phase formed in acetone at a 1,10-phenanthroline (phen):LiClO₄ concentration ratio close to 2:1 was found. According to X-ray diffraction data, the molecular structure of bis(1,10-phenanthroline)lithium perchlorate is as follows: space group Pnna, a 7.191(2), b 39.929(9), c 14.494(3) Å, Z 8, and D _x 1,490 g cm^?3. The IR spectra data show that the complex Li(phen)₂ClO₄ dissociates in acetone into a 1:1 complex and a phen molecule in the solution equilibrium with the solid phase.
