✦ Synopsis

Ethylenediamine trimolybdate, (C 2 H 10 N 2 ) [Mo 3 O 10 ], has been hydrothermally synthesized (180°C, 24 h, autogeneous pressure). It crystallizes in the monoclinic system (space group P2 1 /n) with a ‫؍‬ 8.0865(2) A s , b ‫؍‬ 14.4902(2) A s , c ‫؍‬ 8.9306(2) A s , ‫؍‬ 98.170(1)°, and Z ‫؍‬ 4. Its structure consists of hitherto unknown infinite chains running parallel to the a axis made up of distorted MoO 6 octahedra connected by corners, edges, and faces. Ethylenediamine cations are located between the chains and ensure the connectivity of the structure by hydrogen bonds.
