Abstract: The quaternary complex, [Ce(CH2ClCOO)2(NO3)(phen)(H2O)]2, was synthesized. Interestedly, the title compound is a dimer comparing with the 1Dpolymer [La(CH2ClCOO)2(NO3)(phen)·(H2O)]n and powder compound [Nd(CH2ClCOO)2(NO3)(phen)]. In the title compound there is a monodentate NO3-, which is a first example in the all synthesized quaternary mixed anion complexes, and the NO3- extended the complex into a 2Dnetwork 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—Nbonds 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—Oand Ce—Nbonds, was first found in the series compounds.

Key words: Quaternary complex, Crystal structure, Stacking effect, Network of hydrogen bonds
