Synthesis and crystal structures of two rare-earth metal polymers of olsalazine.

Two 1-D linear coordination polymers, {[Gd2(L)2 · (Phen)2 · 2(H2O) · 2(NO3)] · 2(EtOH)}n (1) (H2L = olsalazine) and {[Eu2(L)2·(Phen)2 · 2(H2O) · 2(NO3)] · EtOH}n (2), were obtained from self-assembly of Gd(NO3)3 · 8H2O or Eu(NO3)3 · 8H2O with olsalazine. Both complexes are 1-D polymers, for 1 with crystal data: P 1, a = 11.651(4), b = 11.865(4), and c = 12.296(4) Å, α = 77.984(4)°, β = 65.559(4)°, and γ = 74.558(5)°, V = 1482.1(8) Å3, Z = 1, R1 = 0.0389, wR2 = 0.0793, and 2 with crystal data: P 1, a = 11.626(3), b = 11.834(3), c = 12.287(4) Å, α = 77.743(3), β = 65.576(3), γ = 74.371(3)°, V = 1472.5(5) Å3, Z = 1, R1 = 0.0609, wR2 = 0.1185. Central atoms (Gd or Eu) in both complexes adopt nine-coordinate tricapped trigonal prism geometry. CCDC No.: 694918 (1), 694919 (2). [ABSTRACT FROM AUTHOR]
