【Abstract】 The quaternary complex, [Ce（CH2ClCOO）2（NO3）（phen）（H2O）]2, was synthesized. Interestedly, the title compound is a dimer comparing with the 1D polymer [La（CH2ClCOO）2（NO3）（phen）·（H2O）]n and powder compound [Nd（CH2ClCOO）2（NO3）（phen）]. In the title compound there is a monodentate NO-3, which is a first example in the all synthesized quaternary mixed anion complexes, and the NO-3 extended the complex into a 2D network with water from other molecules by inter-molecular hydrogen bonds. The intermolecular hydrogen bonds lead to the weaker Ce—O（COO）, Ce—O（NO3） and Ce—N bonds comparing with other quaternary mixed anion complexes of cerium. Also the stacking effect, which makes the compound more stable in the situation of weaker Ce—O and Ce—N bonds, was first found in the series compounds.
