| 2.2.8.8-tetra-ethoxycarbonyI-1.3.7-triarsa-tricyclo[3.3.1.03,7]nonan und 5-Methyl-1.3.7-triarsa-2.8-diselena-tricyclo[3.3.1.03,7]nonan Chemistry of Polyfunctional M olecules, 80 [1] Crystal and M olecular Structures of the H eteronoradam antanes 5-M ethyl-2.2.8.8-tetra-ethoxycarbonyl-1.3.7-triarsa-tricyclo[3.3.1.03'7]nonane and 5-M ethyl-1.3.7-triarsa-2.8-diselena-[3.3.1.037]nonane The m olecular and crystal structures of the nor-heteroadam antanes C H 3C (C H 2A s)3[C (C O O C H ;C H 3)2]2 (1) and C H 3C (C H 2A s)3Se2 (2) have been investigated in order to obtain confirm ation of the rare structures deduced earlier from mass, 'H NM R and vibrational spectroscopy. Crystals of 1 are triclinic, space group P I —Cf with a — 769.27(30), b = 1036.09(14), c = 1599.18(17) pm , a = 98.236(10)°, ß = 97.987(18)°, y = 103.633(20)° and Z = 2. On the basis of 1821 unique reflections the structure was refined to a weighted R value of 5.28% . The crystals of 2 are monoclinic, space group P 2 ,/c—Cih with a = 1102.73(23), b — 727.49(14), c = 1281.27(42) pm . ß = 98.803(21)° and Z = 4. On the basis of 1065 unique reflections the structure was refined to a weighted R value of 5.93%. Several attem pts to synthesize C H 3C (C H :A s)3Te2 failed. | | | |
