| A series of mono and bis N,O-chelate complexes 1-32 with the mono and dianion of indigo and indigo derivatives (R3P)(C1)M(L-H+) (M = Pd.Pt), (r/3-allyl)Pd(L-H+), (PhiC=NCH->CO->Et-H+)Pd(L-H+), (PhN=NPh-H+)Pd(L-H+), (Q H 5)Fe(C5H3CH2NMe2)Pd(L-H+), [(R3P)(Cl)Pt]2(L-2H+), [(//3-allyl)Pd]2(L-2H+), [(C6H4CH2N M e2)Pd]2(L-2H+) with L = indigo, 4,4'-dichloro-, 6,6'-dichloro-, 6,6'-dibromo-, 6,6'-di-»Bu-, 4,4'-dichloro-, 5.5'dibromo-, 5,5', 6,6'-tetramethoxy-, 4.4'-di-S]2H25-, 5,5'-di-SO?Na-indigo, indigo malonic ester and tetrahydro indigo have been prepared from chloro bridged metal complexes. In comparison to the free neutral indigo ligands the complexes show a high bathochromic shift in the VIS spectra (150-300 nm) which is mainly due to the anionic character of the coordinated indigo ligands. The structure of [(Et3P)(Cl)Pt]2(indigo-2H+) has been determined by X-ray diffraction. Metallkomplexe von Farbstoffen, VIII [1] | | | |

| Geschlossene ^ [(PtDy4O i6)4]-Polyedertunnel in Ba13Dy8Zn4Pt4037 Closed ^ [(PtDy40 16)4] Polyhedra Tunnels in Ba13Dy8Zn4Pt40 37 | | | | Abstract
| Single crystals of Bai3Dy8Zn4Pt40 37 have been prepared by reaction of mixtures of BaC03, ZnO and Dy20 3 at temperatures up to 1225 °C using platinum crucibles. X-ray investigations led to a new crystal structure with tetragonal symmetry, space group C4h-I4/m, a = 18.659(7), c = 5.734(2) A, Z = 2. The structure is characterized by P t0 6 and B a06 octahedra as well as by tetragonal Z n 0 5 pyramids and single capped trigonal prisms of oxygen around dysprosium. The remaining barium positions show coordination numbers of nine and ten. The crystal structure has large ^ [(PtDy40)6)4] polyhedra tunnels. Considering the 1 [Ln4O l6]20_ polyhedra groups some parts of the structure show similarities to BaZnLn20 5, B a ^ n 4Ln8Ö2i and Ba2Ln2ZnPt08. | | | |

| Weitere Verbindungen des Bai7Lnj6Zn8Pt4057-Typs mit Ln = Dy More Compounds of the B a17Ln16Zn8Pt40 57 Type with Ln = | | | | Abstract
| Single crystals of B a|7D y16Zn8Pt40 57 (I), Ba17HO|6Zn8Pt40 57 (II), BaI7Er16Zn8Pt4057 (III) and Ba17Y 16Zn8Pt40 57 (IV) have been prepared by high temperature reactions using platinum crucibles. X-ray investigations led to tetragonal symmetry, space group C4h -I4/m, (I) -(IV): a = 22.905(1), 22.840(1), 22.795(1), 22.848(1) Ä and c = 5.728(1), 5.722(1), 5.700(1), 5.709(1) A, Z = 2. The crystal structure is characterized by small square, medium-sized quadrangular and large rectangular tunnels, which are filled by oxygen, barium and zinc. The polyhedra network is discussed with respect to the network of compounds of the Ba13D y8Zn4Pt40 37 type. | | | |
