Abstract: | Iodoplumbates with Polymeric Anions – Synthesis and Crystal Structures of [Na3(OCMe2)12][Pb4I11(OCMe2)], (Ph4P)2[Pb5I12], and (Ph4P)4[Pb15I34(dmf)6] Reactions of PbI2 with NaI in polar organic solvents followed by crystallization with large cations yield iodoplumbate complexes with various compositions and structures. [Na3(OCMe2)12][Pb4I11(OCMe2)] 3 , (Ph4P)2[Pb5I12] 4 and (Ph4P)4[Pb15I34(dmf)6] 7 contain one-dimensional infinite anionic chains of face- or edge-sharing PbI6 or PbI5L (L = acetone, DMF) octahedra. [Na3(OCMe2)12][Pb4I11(OCMe2)] 3 : Space group P1 (No. 1), a = 1120.3(5), b = 1265.3(6), c = 1608.3(8) pm, α = 74.64(4), β = 70.40(4), γ = 85.24(4)°, V = 2071(2) · 106 pm3; (Ph4P)2[Pb5I12] 4 : Space group C2/c (No. 15), a = 787.00(10), b = 2812.0(5), c = 3115.9(5) pm, β = 96.240(13)°, V = 6885(2) · 106 pm3; (Ph4P)4[Pb15I34(dmf)6] 7 : Space group P21/n (No. 14), a = 2278.8(4), b = 1782.6(3), c = 2616.8(4) pm, β = 114.432(13)°, V = 9678(3) · 106 pm3. |
