Novel benzo-18-crown-6 (B18C6) complexes: { [Na(B18C6)](6) [Pt(SCN)(6)] [Pt(SCN)(6)] (SCN)(2) (1) and [K(B18C6)](2) [Pt(SCN)(6)] -4H(2)O (2) were synthesized and characterized by elemental analysis, IR spectra and X-ray diffraction analysis. 1 belongs to rhomobohedral, space group R 3 with cell dimensions: a = b = 1. 9933 (3) nm, c = 2.9760(6) nm, a = beta=90degrees, gamma= 120degrees, V= 10.240(3) nm(3), Z = 3, D-calcd = 1.564 g/cm(3), F(000) = 4908, R-1 = 0. 0535, wR(2) = 0. 1030. 2 is triclinic crystal system, space group P1 with cell dimensions: a = 1. 1692 (3) nm, b = 1. 1853 (4) nm, c = 1.2381 (5) nm, a = 61.419 (5)degrees, beta = 80.757 (8)degrees, gamma = 89.003 (5)degrees, V = 1.4836(9) nm(3), Z = 1, D-calcd = 1.476 g/cm(3), F(000) = 666, R-1 = 0.0696, wR(2) = 0.1346. 1 is composed of one ([Na(B18C6) ](6) [Pt(SCN)(6)]}(4+) complex cation, one [Pt(SCN)(6)](2-) complex anion and two SCN- anions. I [Na(B18C6)](6) [ Pt (SCN)(6)]}(4+) complex cations show a three-dimensional network structure bridged by Na-O interactions between the adjacent [Na(B18C6)] units. The function of [Pt(SCN)(6)](2-) Complex anion and two SCN(-)anions are balancing the charge in the crystal. 2 is made up of two [Na (B18C6)](+) complex cations and one [Pt (SCN) (6) ](2-) complex anion. They form one-dimensional chain structure bridged by K-O interactions between the adjacent [K(B18C6)](+) units.
