HYDROTHERMAL SYNTHESIS AND CRYSTAL STRUCTURE OF ANHYDROUS ETHYLENEDIAMINE TRIMOLYBDATE (C2H10N2)[MO3O10]

摘要

Ethylenediamine trimolybdate, (C2H10N2)[Mo3O10], has been hydrothermally synthesized (180 degrees C, 24h, autogeneous pressure). It crystallizes in the monoclinic system (space group P2(1)) with a=8.0865(2) Angstrom, b=14.4902(2) Angstrom, c=8.9306(2) Angstrom, beta=98.170(1)degrees, and Z=4. Its structure consists of hitherto unknown infinite chains running parallel to the a axis made up of distorted MoO6 octahedra connected by corners, edges, and faces. Ethylenediamine cations are located between the chains and ensure the connectivity of the structure by hydrogen bonds. (C) 1997 Academic Press. [References: 17]
