Abstract: | |
Single crystals of CsPr2(CH3COO)7 were obtained from an acetic acid solution of Pr(CH3COO)3 • H2O and Cs2CO3 in a molar ratio of 4:1 at 120°C. It crystallizes in the triclinic system, PĪ (no. 2), Z = 2, a = 1028.1(5), b = 1034.6(5), c = 1199.4(6) pm, α = 84.82(2), β = 67.07(3), γ = 76.01(2)°, Vm = 343.3(3) cm3/mol, R = 0.031, Rw = 0.027. The crystal structure contains infinite chains, 1∞[Pr2(CH3COO)6], running along the [110] direction. The chains are built up by bridging acetate ions coordinated to two crystallographically different Pr3+ ions which are both surrounded by 9 oxygen ligands. These chains are linked by “intercalated” Cs(CH3COO) to layers parallel (100). Cs+ has contacts to oxygen atoms of neighbouring layers, such that a three-dimensional network is formed. | |
