Synthesis and crystal structure of Ca2Ag1.83Al 0-67Ge1-50 - A solid solution with the NbCoB-type structure

Ponou, Simeon LU and Lidin, Sven LU (2009) In Zeitschrift fur Anorganische und Allgemeine Chemie 635(13-14). p.2143-2146
Abstract

The crystal structure of the new phase, Ca2Ag 1.83Al0.67Ge1.50(1) (1) was determined by single-crystal X-ray diffraction, after the compound was obtained by high temperature synthesis technique. 1 crystallizes with the NbCoB type structure in the orthorhombic space group Pmmn (no. 59) with unit cell parameters: a = 20.505(1) Â, b = 4.3807(2) Å c = 7.2211(3) Å, V= 648.65 Å3 (Z = 5). The structure of the title compound represent a rare intergrowth of the well known KHg2 (or CeCu2) and Fe2P type structures.
