| Zur Darstellung und Kristallstruktur von Na2CuAs, K2CuAs und K2CuSb Preparation and Crystal Structure of Na2CuAs, K2CuAs and K2CuSb  | | | Abstract
| The three new compounds crystallize orthorhombic, space group Cmcm with Na2CuAs: a = 8.86(2) A, b = 7.22(2) A, c = 5.34(2) A; K2CuAs: a = 10.02(2) A, b = 7.56(2) A, c = 5.89(2) A; KsCuSb: a = 10.50(2) A, b = 7.93(2) A, c = 6.23(2) A. There are Cu-E(V)-Cu-E(V)-zigzag-chains in the structure, in which the Cu-atoms are linearly bonded to the E(V)-atoms. | | |

| Neue intermetallische Verbindungen im arcJi-Ce202S-Strukturtyp New Intermetallic Compounds in the awfa"-Ce202S-Structure Type  | | | Abstract
| The new intermetallic compounds CaMn2Sb2, SrMn2Sb2 and CaMn2Bi2 have been prepared and structurally characterized. They are isotypic and crystallize trigonal in the an^-Ce202S-structure with the lattice constants: CaMn2Sb2: a = 4.54(1), c = 7.48(1), c/a = 1.65. SrMn2Sb2: a = 4.56(1), c = 7.70(1), c/a = 1.69. CaMn2Bi2: a = 4.63(1), c = 7.64(1), c/a = 1.65. | | |

| G e r h a r d C o r d i e r u n d H e r b e r t S c h ä f e r BaMnSb2, SrMnBi2 and BaMnBi2 have been prepared and structurally characterized. The new compounds are isotypic and crystallize tetragonal in the SrZnBi2 structure with the following constants: BaMnSb2: a = 4.53 ± 0.01 A, c = 24.34 ± 0.03 A, c/a = 5.37. SrMnBi2: a = 4.58 ± 0.01 A , c = 23.13 ± 0.03 A, c/a = 5.05. BaMnBi2: a — 4.63 ± 0.02 A, c = 24.22 i 0.05 A, c/a = 5.23. The transition metal atoms form together with the semimetal atoms sheets of tetragonal pyramids separated by double layers of alkali earth atoms. In these double layers there are inserted Bi/Sb-square nets. | | |
