Single crystals of octa-deca-nickel dodeca-germanide were grown by chemical transport reaction. The inter-metallic compound crystallizes in a superstructure of the hexa-gonal NiAs type (B8 type). All atoms in the asymmetric unit lie on special positions except one Ni atom (two Ni atoms have site symmetry -6.. and another one has site symmetry .2. while the(More)
Single crystals of anti-mony-doped germanium, Ge1-x Sb x+0.01 (x ≃ 0.0625), were grown by chemical transport reaction. The alloy crystallizes as a superstructure of diamond-type α-Ge. All atoms in the asymmetric unit lie on special positions and are characterized by strong covalent bonds. The anti-mony atoms substitute for one germanium atom at full(More)
Single crystals of the mercury chalcohalide Hg3-x Sb x (S+Se)2+x I2-x (x ≃ 0.1) (mercury anti-mony sulfide selenide iodide), were grown by a chemical transport reaction. The structure contains three independent A (Hg/Sb) atoms; each atom is strongly covalently bonded with two X (Se/S) atoms to form approximately linear X-A-X units. The X-A-X units link to(More)
