CsPr2(CH3COO)7, ein caesiumarmes wasserfreies ternäres Caesium-Praseodym-Acetat

Single crystals of CsPr 2 (CH 3 COO) 7 were obtained from an acetic acid solution of Pr(CH 3 COO) 3 .H 2 O and Cs 2 CO 3 in a molar ratio of 4: 1 at 120 o C. It crystallizes in the triclinic system, P 1 (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) o , V m =343.3(3) cm 3 /mol, R=0.031, R w =0.027. The crystal structure contains infinite chains, ∞ 1 [Pr 2 (CH 3 COO) 6 ], running along the [110] direction
