 Title    Iodomanganate(II): Darstellung und Kristallstrukturen von (Ph 4 P)MnI 3 L, MnI 2 L 3 , [MnIL 5 ]I 3 und [MnL 6 ](I 3 ) 2 (L = Tetrahydrofuran) Iodomanganates(II): Synthesis and Crystal Structures of (Ph 4 P)MnI 3 L, MnI 2 L 3 , [MnIL 5 ]I 3 and [MnL 6 ](I 3 ) 2  
 Abstract    The compounds (Ph 4 P)MnI 3 L (1), MnI 2 L 3 (2), [MnIL 5 ]I 3 (3), and [MnL A ](I 3) 2 (4) (L = C 4 H H O, thf) were prepared in thf solution and their structures determined from single crystal X-ray diffraction data. 1 crystallizes in the monoclinic space group C2/c with a = 1743.6(1), b — 1985.8(1), c = 1806.7(1) pm, ß = 98.74(1)°, Z = 8. The structure of 1 exhibits tetrahedral anions. The Mn—I distance was found to be 268.0 pm (mean). 2: monoclinic, C2/c with a = 1252.3(2), b = 1255.0(3), c = 1271.8(3) pm ß = 113.88(2)°, Z = 4. The characteristic feature of the structure of 2 is the existence of neutral MnI 2 L 3 molecules with a distorted trigonal bipyramidal geometry and the iodine atoms in equatorial positions (Mn —I: 271.1 pm). The compound crystallizes from a solution of Mnl 2 in tetrahydrofuran. 3: monoclinic, C2/c with a = 1695.3(1), b = 1123.1(1), c = 1646.2(1) pm, ß = 96.91(1)°, Z = 4. The preparation of 3 from 2 and iodine yields octahedral MnIL, + cations (Mn —I: 278.8 pm) and triiodide anions. 4: monoclinic, P2,//z with a = 1005.5(1). b = 1056.8(1), c -1835.6(2) pm, ß = 91.16(1)°, Z -2. 4 is prepared from 3 and iodine in thf solution, and shows octahedral MnL 6 2+ cations and triiodide anions.
