Popis:	In [(CH3)(C6H5)SnCl2 · H2O]2 ·18-crown-6 C26H44Cl4O8Sn2 (triclinic, P[unk], a = 9.727(1) Å, b = 10.236(2) Å, c = 11.077(2) Å, α = 64.22(2)°, β = 87.42(2)°, γ = 62.65(2)°) a chlorine bridge (Sn–Cl = 3.403(3) Å) links two adjacent (CH3)(C6H5)SnCl2 · H2O units together to form a ccntrosymmetric dimer having an Sn–Cl … Sn–Cl ring; the tin atom occupies a distorted trans-octahedral (C–Sn–C = 147.8(1)°) site. The coordinated (Sn–O = 2.363(2) Å) water molecule forms twin, bifurcated hydrogen bonds with the crown ether molecule.
