Abstract
Two benzo-18-crown-6 (B18-C-6) complexes: [Na(B18-C-6)]2[Pd(SCN)4](H2O)({bf 1}) and [Na(B18-C-6)]2[Pt(SCN)4]...0.5C2H4C12 (2)have been synthesized and characterized by elemental analysis, IR spectrum and X-raydiffraction analysis. The crystal of complex 1 belongs to monoclinic, space group P21/n with cell dimensions, a = 1.0481(3), b = 1.2864 (3), c = 1.7003 (4) nm, β = 93.626(4)°, V = 2.2879 (9) nm3, Z = 2, Dcalcd = 1.491 g/cm3, F(000) = 1060, R1 = 0.0562, wR2 = 0.1412 and 2 is triclinic, spacegroup P1 with cell dimensions, a = 0.9581(3), b = 1.2173 (3), = 2.1198 (6) nm, α = 79.522(4), β = 77.911(4), γ = 78.617(4)°, V = 2.3442(11) nm3 Z = 2, Dcalcd = 1.626 g/cm3, F(000) = 1154, R1 = 0.0515, wR2 = 0.0612.Two complexes show one-dimensional chain of [Na(B18-C-6)]+ complex cations and [M(SCN)4]2- (M = Pd, Pt) complex anion bridged by Na–O–Na interactions of H2O molecule or Na-O bond of B18-C-6 between adjacent [Na(B18-C-6)]+ units respectively.
