摘要：

Two new bimetallic sulfides, (Haep)(2)center dot Ga(2)Sb(2)S(7) (1) and Mn(2)(phen)Sb(2)S(5) (2), have been synthesized under solvothermal conditions, where aep = 1-(2-aminoethyl)piperazine and phen = 1,10-phenanthroline. The structure of 1 consists of GaS(4) tetrahedra and SbS(3) trigonal pyramids and has a layered structure with 8-membered-ring windows. Interestingly, the interlayer organic cations form helices through extensive hydrogen bonds. Compound 2 has a neutral layered structure containing infinite Mn-S sheets. The organic species are attached directly to Mn atoms within the layers by covalent bonds and protrude into the interlayer region. Both compounds 1 and 2 exhibit intense photoluminescence upon photoexcitation at 360 nm. Magnetic susceptibility measurements demonstrate the existence of antiferromagnetic interactions in compound 2. Crystal data: 1, orthorhombic, P2(1)2(1)2(1) (No. 19), a = 9.9274(2) angstrom, b = 12.9201(3) angstrom, c = 21.2254(4) angstrom, V = 2722.43(10) angstrom(3), Z = 4; 2, monoclinic, P2(1)/c (No. 14), a = 12.6385(3)angstrom, b = 12.3998 (3) angstrom, c = 12.3670(3) angstrom, beta = 111.8240(10)degrees, V= 1799.19(7) angstrom(3), Z 4.
