  摘要：

  Four novel Ag-I-complexes with DL-mandelic acid (MA) (1), squaric acid (H(2)Sq) (2), 3-pyridin aldehyde (3PyA) (3) and 2-amino-8-hydroxyquinoline (2A8H) (4) as well as two Zn-II-ones with 3PyA (5) and 2A8H (6) are synthesized, isolated, spectroscopic and structural characterized by single crystal X-ray diffraction, UV-vis-NIR, and IR-spectroscopy. The experimental data of the complex (1) were compared with the analogous of the neutral MA. Quantum chemical calculations are carried out, and the electronic structures and optical properties of neutral MA and its anion, with a view to assign the vibrational properties of (1).

  combining these cations with racemic mandelate or hydratropate anions, but four less popular products, namely three double salts and a solid solution, were obtained and structurally characterized. For one of the double salts, the alternative ionic compounds based on different stereoisomers of the same residues were synthesized independently: The conventional racemic solid and both diastereomeric salts
