Abstract:
Potassium indium diarsenate(V) was grown under mild hydrothermal conditions (T = 493 K, 7 d) at a pH value of about 1. It adopts the TlInAs₂O₇ structure type (P-1, Z = 4) and is closely related to the KAlP₂O₇ (P2'-{1}/c) and RbAlAs₂O₇ (P-1) structure types. The framework topology of KInAs₂O₇ is built of two symmetrically non-equivalent As₂O₇ groups which share corners with InO₆ octahedra. The K atoms are located in channels extending along [010].
