One-Dimensional Chain Crown Ether Complexes: Syntheses and Crystal Structures of [K(B18-C-6)]_2[M(SCN)_4] (M = Pd, Pt)

The reactions of benzo-18-crown-6 (B18-C-6) with K_2M(SCN)_4] (M = Pd, Pt)were studied and the complexes K(B18-C-6)]_2 Pd(SCN)]_4 (1), K(B18-C-6)]_2 Pt(SCN)_4] (2) and K(B18-C-6)]_2Pt(SCN_4]·C_2H_4Cl_2] (3) were characterized by elemental analysis, IR and X-ray diffraction analysis. 1 and 2 belong to monoclinic, space group P2_l/n with crystal data: 1, a = 1.00970(17) nm, b = 1.3157(2) nm, c = 1.7303(3) nm, β = 94.954(2)°, V = 2.2902(7) nm~3, Z = 2, F(000) = 1072, R_1 = 0.0627; 2, a = 1.00908(18) nm, b = 1.3124(2) nm, c = 1.7317(3) nm, β = 94.841(2)°, V = 2.2852(7) nm~3, Z = 2, F(000) = 1136, R_1 = 0.0257. 3 belongs to triclinic, space group P1 with crystal data: a = 0.95914 (18) nm, b = 1.2137(2) nm, c = 1.2313(2) nm, α = 63.693(2)°, β = 76. 293(2)°, γ = 78.353(2)°, V=1.2406(4) nm~3, Z = 1, F(000) = 618, R1 = 0.036. In the solid state, the complexes exhibit one-dimensional chain structure of two K(B18-C-6]~+ complex cations bridged by K atom and O atom of crown ether between adjacent complex cations.
