Pt(II) 18-crown-6 complex [K(18C6)](2)[Pt(SCN)(4)](H2O) has been isolated a
nd characterized by X-ray diffraction analysis. The crystal structure belon
gs to monoclinic, space group P2(1)/n with cell dimensions, a = 1.1116(1),
b = 1.2258(1), c = 1.5856(1) nm, beta = 93.479(9)degrees, V= 2.1567(3) nm(3
), Z = 2, R = 0.033 and Rw = 0.051. In the solid state, the complex display
s a one-dimensional infinite chain of two [K(18C6)](+) complex cations and
a [Pt(SCN)(4)](2-) anion bridged by one H2O molecule between adjacent [K(18
C6)](+) units.
