Abstract: The title compounds [MS4Cu4(SCN)2(NC5H5) 6] (M=W (1); M=Mo (2); NC5H5=pyridine) were obtained by the reaction of (NH4)2MS4, CuSCN, KSCN and pyridine. The X-ray analyses of 1 and 2 show that four edges of the tetrahedral MS4 2- core are coordinated by four copper atoms, giving an MS4Cu4 aggregate of approximate D2h symmetry. The nonlinear optical properties of 1 and 2 were investigated by a Z-scan technique with 7 ns laser pulses of 532 nm. The third-order nonlinearities were determined with α2=4.3×10-5 and 4.1×10-5 cm W-1 M-1; and n2=-4.3×10-10 and -4.1×10-10 cm2 W-1 M-1, respectively, for compounds 1 and 2. © 1999 Elsevier Science S.A.
