Abstract:
First single crystals of Na 2 [{(ON)Ce 4 }Cl 9 ] were obtained during synthesis attempts for the cerium nitride chloride Ce 2 NCl 3 (= {N 2 Ce 4 }Cl 6 ). With a molar ratio of 8:10:3 for Ce, CeCl 3 and NaN 3 along with an excess of the flux NaCl, the mixture obviously contained a small amount of CeOCl that led to the formation of quinary Na 2 [{(ON)Ce 4 }Cl 9 ]. It crystallizes in the monoclinic space group P 2 1 / m (no. 11) with two formula units in the unit cell with dimensions of a = 813.21(6) pm, b = 1146.13(9) pm, c = 942.86(7) pm and β = 107.504(5) °. As the dominating structural feature { Z Ce 4 } 9.5+ tetrahedra are fused through trans ‐oriented edges to generate ${}^1_\infty\{\textit{Z}\textrm{Ce}^\textrm{e}_{4/2}\}^{3.5+}$ chains ( Z = 1 / 2 O + 1 / 2 N) just as in the structurally isotypic compounds A 2 [{ Z 2 R 4 } X 9 ] ( A = Na, K; R = Pr, Nd, Gd; X = Cl, Br; Z = O, O/N).
