| Darstellung, Kristallstrukturdaten und Eigenschaften der quaternären Thiostannate(IV) BaZnSnS4 und BaMnSnS4 Preparation, Crystal Data and Properties of the Quaternary Thiostannates(IV) BaZnSnS4 and BaMnSnS4  | | | | Abstract
| BaZnSnS4 and BaMnSnS4 were prepared for the first time and the atomic positions of the crystal structure were refined. Both compounds crystallize isotypically with BaCdSnS4 [1]. Space group C^-Fdd2 (No. 43) orthorhombic. BaZnSnS4: a = 2196,4; b = 2150,4; c = 1270,i pm; BaMnSnS4: a = 2173,i; b = 2144,9; c -1259,i. | | | |

| Zur Kenntnis der Hydrate des Mangan-und Zinksulfits. Röntgenographische, thermoanaly tische, Raman-und IR-spektroskopische Untersuchungen | | | | Abstract
| X-ray, IR and Raman data as well as thermoanalytical measurements (DTA, TG, and DTG) of several new hydrates, viz. MnS03 • 2 1 /z H20, MnS03 • 2 H20, ZnS03 • 3 H20, /S-ZnS03 • 2 1 /2 H20, and y-ZnS03 • 2 x /2 H20, and of previously reported hydrates in the systems MnS03-H20, ZnS03-H20, and MnS03-ZnS03-H20 are presented. Furthermore, the formation of mixed crystals is studied in the system MnS03-ZnS03-H20. The following crystal data have been determined by single crystal measurements: MnS03 • 2 1 /2 H20 (P4i2i2):a = b = 968.4(1), c = 1040.9(1) pm, Z = 8, MnS03 • 2 H20 (P2i/w):a = 650.9(1), b = 873.8(1), c = 774.7(1) pm, ß = 99.80(1)°, Z = 4, ZnS03 • 3 H20 (Pnma): a = 953.6(1), b = 553.0(1), c = 941.9(1) pm, Z = 4, ß-ZnS03 • 21/2 H20 (P4i2!2): a = b = 952.1(1), c = 1025.4(1) pm, Z = 8, y-ZnS03 • 2 X \2 H20 (with small amount of Mn 2 +) (o-rh.): a = 1493(1), b = 1812(2), c = 753(1) pm, Z = 16, ZnS03 • 1/2 H20 (mon.): a = 1326.7(5), b = 706.3(2), c = 834.4(1) pm, ß = 117.41(3)°, Z = 8. The IR spectra show that, with the exception of y-ZnS03 • 2 x /2 H20, both weak and strong hydrogen bonds are present in the sulfite hydrates. Under an S02 atmosphere the sulfite hydrates can be dehydrated without simultaneous dissociation to the oxide and sulfur dioxide. The isotypic hydrates /?-MnS03 • 3 H20 and ZnS03 • 3 H20 (ß-MnSÖ3 • 3 H20 type), and MnS03 • 2 H20 and ZnS03 • 2 H20 (ZnSe03 • 2 H20 type) form complete mixed crystal series. Solid solutions are also formed from a-MnS03 • 3 H20 (a-FeS03 • 3 H20 type), y-ZnS03 • 2 l /2 H20, MnS03 • 1 H20, and ZnS03 • 1 /2 H20. No incorporation of Mn or Zn could be observed for a-ZnS03 • 2Va H20 and the isotype hydrates MnS03 • 2!/a H20 and ß-ZnS03 • 2 1 /2 H20 (CoS03 • 21/2 H20 type). | | | |

| Acetylaceton als Dien-Diolat-Ligand in 6-Methyl-4-methylen-2-phenyl-4H-1.3.2-dioxa-arsorin- Übergangsmetallkomplexen Acetylacetone as a Diene Diol Ligand in 6-Methyl-4-methylen-2-phenyl-4H-l,3,2-dioxa-arsorine Transition Metal Complexes | | | | Abstract
| of dichlorophenylarsane complexes with acetylacetone gives 1,3,2-dioxa arsorine systems, in which both chlorine functions are substituted by the oxygen atoms of one acetylacetone moiety bonded in its diene diol form. Properties and spectra of (C0)5CrAsPh(C5H602) and 7?5.c5H5(C0)2MnAsPh(C5H602) are described; the structure of the (CO)öCr complex was established by an X-ray analysis. | | | |
