Abstract

Five new thiogallates have been prepared solvothermally in the presence of ethylenediamine and characterized by single-crystal X-ray diffraction, thermogravimetry, and elemental analysis. [enH2][Ga4S 7(en)2] (1), which crystallizes in the monoclinic space group P21/c with lattice parameters a = 12.8698(12) Å, b = 10.4812(9) Å, c = 16.5473(14) Å and ß = 102.457(4)° (Z = 4), exhibits a layered structure in which both covalently and hydrogen-bonded template molecules coexist. The structures of [M(en)3] 0.5[GaS2] (M = Mn (2) (orthorhombic, Cmcm, a = 9.5555(6) Å, b = 15.0696(10) Å, c = 12.2893(7) Å, Z = 8) M = Co (3) (orthorhombic, Cmcm, a = 9.4660(7) Å, b = 15.0990(11) Å c = 12.2540(8) Å, Z = 8), M = Ni (4) (orthorhombic, Cmcm, a = 9.4510(10) Å, b = 15.1416(15) Å, c = 12.2387(11) Å, Z = 8)) and Mn(en)2Ga2S4 (5) (monoclinic, C2/c, a = 14.3002(11) Å, b = 7.9509(5) Å, c = 12.1184(6) Å, ß = 100.191(4)°, Z = 4) are closely related and contain one-dimensional [GaS2]- chains, which are separated by [M(en) 3]2+ counterions in 2, 3, and 4, and linked into a three-dimensional structure by [Mn(en)2]2+ units in 5. © 2006 American Chemical Society.
