| [AlX4/2 3 ] und i |InP4/23 ]: Synthesen, Kristallstrukturen und Schwingungsspektren von Na3|AlX2], K2Na[AlX2] und K3IInP2] (X = P, As) Com pounds with SiS2 Isoelectronic Anions l [A1X4 23-] and i [InP4/23-]: Synthesis, Crystal Structures and Vibrational Spectra of N a3[AlX2], K 2Na[AlX2] and K 3[InP2] (X = P, As) The title compounds were prepared from stoichiometric mixtures o f the elements or from alkali metals (Na, K), NaX (KX) and MX (M = Al, In; X = P, As) at 1000 K. The crystal structures (Ibam, No. 72) are characterized by infinite chains o f edge sharing tetrahedra j, [MX4;,3'] (M = Al, In; X = P, As) which are isoelectronic to SiS2. The vibrational spectra can be interpreted with respect to the symmetry P(2/m 2/c) 42/ m -D 4h of the isolated polymeric chain ][M X 4(23"]. The assignment of the observed frequen cies is supported by a normal coordinate analysis using the fragment method. | | |
