%X The synthesis, and crystal and molecular structure of N,N&#8242;- diphenylguanidinium m- chlorobenzeneseleninate (C19H18CIN3O2Se), Mr 434.78, are reported. The crystal lattice of the compound belongs to the monoclinic space group P21/c with a 7.277(1), b 12.793(2), c 20.013(4) &#506;, &#946; 94.733(12)&#176;, V 1859.8 &#506;3, Z 4, Dobs 1.53 (by flotation), Dcalc 1.555 g cm-3, &#955;(Mo K&#945; ) 0.71069 &#506;, &#956; 21.0 cm-1, F(000) 880, T 293 K, R 0.057 and Rw 0.059 for 1745 unique observed reflections with I>2.0&#963;(I). The crystal packing consists of parallel layers of anions intercalated with cations interacting through electrostatic contacts. Vibrational spectra have been also recorded, and are discussed.
