摘要:
New complexes of composition [Bi(DMSO)(8)][Fe(NCS)(6)] (1) and [Al(DMSO)(6)][Al(NCS)(6)] (2) have been prepared, and an octahedral hexarodanoaluminate anion has been structurally characterized for the first time. Crystals of compound 1 are triclinic, space group P(1)over bar, a = 11.2368(4) , b = 11.4063(4) , c = 21.0711(9) , alpha = 92.9520(10)A degrees, beta = 99.9430(10)A degrees, gamma = 111.9290(10)A degrees, V = 2447.69(16) (3), Z = 2, rho(calc) = 1.680 g/cm(3), R (1) = 0.0564; crystals of compound 2 are cubic, space group Pa(30 over bar, a = 15.8201(4) , V = 3959.39(17) (3), Z = 4, rho(calc) = 1.462 g/cm(3), R (1) = 0.0475. The bismuth coordination polyhedron BiO8 in compound 1 is a distorted square antiprism with broken square faces (Bi-O, 2.368-2.582 ). In the structure of 2, the cation disordered in a complex manner has an octahedral configuration (Al-O, 1.888(11)-1.912(11) ).
