Crystals of K2Pt(CN)4Br2, K 2Pt(CN)4I2 and K2Pt(CN) 4Cl2·2H2O were grown, and their crystal structures have been determined from single crystal data. The structure of K2Pt(CN)4Cl2 has been determined and refined from X-ray powder data. All compounds crystallize monoclinicly (P2 1/c; Z = 2), and K2Pt(CN)4X2 with X = Cl, Br, I are isostructural. K2Pt(CN)4Cl2: a = 708.48(2); b = 903.28(3); c = 853.13(3) pm; β = 106.370(2)°; R p = 0.064 (N(hkl) = 423). K2Pt(CN)4Br 2: a = 716.0(1); b = 899.1(1); c = 867.9(1) pm; β = 106.85(1)°; R(F)N′ = 0.026 (N′(hkl) = 3757). K 2Pt(CN)4I2: a = 724.8(1); b = 914.5(1); c = 892.1(1) pm; β = 107.56(1)°; R(F)N′ = 0.025 (N′(hkl) = 2197). K2Pt(CN)4Cl2· 2H2O: a = 763.76(4); b = 1143.05(6); c = 789.06(4) pm; β= 105.18(1)°; R(F)N′ = 0.021 (N′(hkl) = 2281). Raman and infrared spectroscopy data are reported.
