The title compounds [MoS{sub 4}Cu{sub 6}X{sub 4}(PY){sub 4}]{sub n} (1:X=Br; 2: X=I) were obtained by the reaction of [NH{sub 4}]{sub 2} [MoS{sub 4}], CuX, and [Bu{sup n}{sub 4}N]X (X=Br, I) in the solid state and pyridine substitution of the solid state product in acetonitrile. Dark crystals of 1 are tetragonal, space group I42d with unit cell parameters a=14.611 (3), c=15.119 (13) {angstrom}; V=3227.1 {angstrom}{sup 3}; Z=4, D{sub calc}-2.55 g cm{sup -3}, R=0.030 for 586 observed reflections. The X-ray analysis confirms that the structure, which possesses a crystallographic 4 symmetry axis situated at the Mo atom, consists of a tetrahedral MoS{sub 4} core enveloped by an octahedral array of six copper atoms, forming an MoS{sub 4}Cu{sub 6} aggregate. Linked by -Cu{sub eq}-Br-Cu{sub eq}- bridges, this aggregate connects with its nearest, neighbours and develops a two-dimensional network. The Mo-Cu lengths range from 2.654(1) to 2.668(1) {angstrom}. 25 refs., 3 fig., 3 tab.
