Two benzo-15-crown-5 (B15-C-5) complexes: [Na(B15-C-5)]_2[Pd(SCN)_4] (1) and {[Na(B15-C-5)[Na(B15-C-5)(H_2O)]}[Pt(SCN)_4] (2) have been synthesized and characterized by IR, elemental analysis, X-ray diffraction analysis. 1 belongs to monoclinic, space group P2_1/n with cell dimensions: a = 1.0164(6) nm, b = 1.3743(3) nm, c = 1.4987(7) nm, β = 95.248(6)°, V = 2.0847 nm~3, Z = 2, D_(calcd) = 1.47 g/cm~3, F (000) = 944, R = 0.053, wR = 0.072. 2 is triclinic crystal system, space group P(1-bar) with cell dimensions: a = 1.1484(2) nm, b = 1. 4210(3) nm, c = 1.5026(3) nm, α = 62.500(3)°, β = 72.393(3)°, γ = 73.106(4)°, V = 2.0398(7) nm~3, Z = 2, D_(calcd) = 1.674 g/cm~3, F (000) = 1028, R_1 = 0.0327, wR_2 = 0.0885. 1 is composed of two [Na(B15- C-5)]~+ complex cations and one [Pd(SCN)_4](2-) complex anion. Complex cations and complex anion form neutral complex through Na-N interactions. Two [Na(B15-C-5)]~+ are trans-orientation with respect to Pd atom. 2 is made up of [Na(B15-C-5)]~+ and [Na(B15-C-5)(H_2O)]~+ complex cations and one [Pt(SCN)_4]~(2-) complex anion. They also form neutral complex through Na-N interactions. [Na(B15-C-5)]~+ and [Na(B15- C-5)(H_2O)]~+ are cis-orientation with respect to Pt atom. Two molecules of 2 form dimer structure though hydrogen bonds of H_2O and N atom of SCN group.
