Studies on Polyhalides. 28. Further Investigations on 1,3,5‐Trialkyl‐tetrahydro‐1,3,5‐triazinium Polyiodides RTazI x : Preparation and Crystal Structure Analysis of the Compounds EtTazI 3 , i‐PrTazI x with x = 3 and 5 and t‐BuTazI x with x = (1), 3, 5 and 7 The salts RTazI x with R = Et, i‐Pr and t‐Bu and 3 ⩽ x ⩽ 7 are formed by the reaction of 1,3,5‐trialkyl‐tetrahydro‐1,3,5‐triazinium iodide RTazI with iodine I 2 from ethanoleous solution. 1,3,5‐Triethyl‐tetrahydro‐1,3,5‐triazinium triiodide C 9 H 20 N 3 I 3 crystallizes triclinically in P 1 with a = 773.5(1) pm, b = 842.8(1) pm, c = 1370.4(3) pm, α = 94.16(1)°, β = 97.34(1)°, γ = 106.35(1)° and Z = 2. The crystal structure is stacked by layers of cations EtTaz + and of linear symmetric triiodide ions I 3 − alternating along [0 0 1]. 1,3,5‐Tri‐iso‐propyl‐tetrahydro‐1,3,5‐triazinium triiodide C 12 H 26 N 3 I 3 crystallizes triclinically in P 1 with a = 822.0(1) pm, b = 832.1(2) pm, c = 1553.6(2) pm, α = 78.26(1)°, β = 76.21(1)°, γ = 77.23(1)° and Z = 2. The crystal structure is built up from layers of cations i‐PrTaz + and of linear symmetric triiodide ions I 3 − alternating along [0 0 1]. 1,3,5‐Tri‐iso‐propyl‐tetrahydro‐1,3,5‐triazinium pentaiodide C 12 H 26 N 3 I 5 crystallizes monoclinically in P2 1 /c with a = 1015.4(2) pm, b = 1278.9(1) pm, c = 1811.3(2) pm, β = 92.47(1)° and Z = 4. The cationic (i‐PrTaz + ) and anionic (isolated V‐shaped I 5 − ) double layers alternate along [0 0 1]. 1,3,5‐Tri‐tertiary‐butyl‐tetrahydro‐1,3,5‐triazinium iodide C 15 H 32 N 3 I crystallizes monoclinically in P2 1 /n with a = 863.9(1) pm, b = 1655.9(2) pm, c = 1307.6(1) pm, β = 92.90(1)° and Z = 4. Mixed layers built up from cations t‐BuTaz + and anions I − follow along [0 1 0]. 1,3,5‐Tri‐tertiary‐butyl‐tetrahydro‐1,3,5‐triazinium triiodide C 15 H 32 N 3 I 3 crystallizes orthorhombically in Fdd2 with a = 1772.0(4) pm, b = 2477.8(6) pm, c = 2273.4(5) pm and Z = 16. The crystal structure is stacked by mixed layers of cations t‐BuTaz + and linear symmetric anions I 3 − . 1,3,5‐Tri‐tertiary‐butyl‐tetrahydro‐1,3,5‐triazinium pentaiodide C 15 H 32 N 3 I 5 crystallizes monoclinically in C2/m with a = 1219.5(3) pm, b = 1420.9(3) pm, c = 1539.5(3) pm, β = 94.54(2)° and Z = 4. The crystal structure is built up from alternating cationic (t‐BuTaz + ) and anionic (symmetry generated I 5 − ) double layers along [1 0 0]. The triiodide parts of different anionic double layers are linked up by iodine bridges I 2 to zickzack chains. 1,3,5‐Tri‐tertiary‐butyl‐tetrahydro‐1,3,5‐triazinium heptaiodide C 15 H 32 N 3 I 7 crystallizes monoclinically in P2 1 /c with a = 1036.0(2) pm, b = 1768.3(4) pm, c = 1699.5(4) pm, β = 103.11(2)° und Z = 4. The crystal structure shows a three‐dimensional network made by the alternating linkage of trigonal‐pyramidal and Z‐shaped heptaiodide ions.
