The crystal structure of La(H 2 O) 2 K(C 2 O 4 ) 2 ' H 2 O has been solved ab initio from powder di4raction data collected with conventional monochromatic X-rays. The symmetry is monoclinic, space group C2/m, cell dimensions a ؍ 22.033(1) A > , b ؍ 7.6003(5) A > , c ؍ 6.6418(4) A > , ؍ 103.8
The title compounds can be prepared either by reacting Fe 3 MoO 4 and Co 3 MoO 4 in a NH 3 stream at 750-900 • C or by plasma nitridation of the oxide precursors (N 2 /H 2 plasma generated with a 1.2 kW microwave source). Fe 3 Mo 3 N and Co 3 Mo 3 N are found to be isostructural with η-Fe 3 W 3 C, w
