Seven lanthanide-metal chalcogenides have been synthesized by the flux-growth method. The first four compounds are BaLn2Se4 (1) (Ln=Nd, Sm, Gd, Er) , which crystallize in the same structure as orthorhombic Pnma. The unit cell constants is a=12.6267(6)Å, b=4.3259(2)Å, and c=15.4277(7)Å for the Nd compound. Structure(1) adopts a three-dimensional framework, in which the [Gd4Se11] layers are fused along the a axis. The fifth compound Ba3Cu4Gd6Se14 (2) crystallizes in monoclinic C2/m with a=14.0489(16)Å, b=4.1560(5)Å, c=12.9449(15)Å, and β=105.207(2)°. Structure (2) adopts a three-dimensional framework , in which the [Gd2CuSe6] layers are fused along the a axis. The sixth compound Ba2InGdSe5 (3) crystallizes in orthorhombic Cmc21 with a=4.2821(3)Å, b=18.8355(12)Å, c=13.3188(8)Å. Structure (3) adopts a one-dimensional structure, in which GdSe6 octahedra share edges with InSe4 tetrahedra to form a [InGdSe5] chain along the c axis. The seventh compound Mn1.7In1.2GdSe5 (4) crystallizes in orthorhombic Cmcm with a=3.9643(5)Å, b=13.1014(16)Å, c=16.586(2)Å. In this structure MSe6(M=Mn/In) octahedra and MnSe6 octahedra share edges to form [M2MnSe6] (M=Mn/In) blocks. These blocks are extended along the c axis to form a three-dimensional framework.
