AbstractThe new compounds LiK[C(CN)3]2 and Li[C(CN)3]·½ (H3C)2CO were synthesized and their crystal structures were determined. Li[C(CN)3]·½ (H3C)2CO crystallizes in the orthorhombic space group Ima2 (no. 46) with the cell parameters a=794.97(14), b=1165.1(2) and c=1485.4(3) pm, while LiK[C(CN)3]2 adopts the monoclinic space group P21/c (no. 14) with the cell parameters a=1265.7(2), b=1068.0(2) and c=778.36(12) pm and the angle β=95.775(7)°. Single crystals of K[C(CN)3] were also acquired, and the crystal structure was refined more precisely than before corroborating earlier results.

Abstract Pd2OCl2 was obtained by reaction of γ-PdCl2 and PdO·nH2O in a KNO3/NaNO3 melt at 450 °C. Single crystals were grown from a TlCl flux. The crystal structure of the tetragonal compound (a = 631.3(2) pm, c = 987.2(2) pm, space group I41 /amd) is built up from bands of edge shared square planar PdO2Cl2 groups connected by common O-atoms to a framework. The relationship between the structures of Pd2OCl2 and PdO is discussed.

The crystal structure of Te(N3)3SbF6 containing the first binary tellurium–nitrogen cation, triazidotellurium(IV) (Te(N3)3+), has been determined by X-ray crystallography. Single crystals of Te(N3)3SbF6 are monoclinic, space group P21/c with a = 9.201(6), b = 8.445(4), c = 13.582(7) Å, β = 100.36(5)°, Z = 4, final R1 = 0.036 for 1286 observed reflections. The structure consists of discrete Te(N3)3+ cations and distorted octahedral SbF6− anions, with some cation–anion interactions. The average Te—Nα—Nβ—Nγ bond distances in Te(N3)3+ are Te—Nα, 1.994(7); Nα—Nβ, 1.237(11); and Nβ—Nγ, 1.116(12) Å. The average bond angles about the Te, Nα, and Nβ atoms are 94.1(3)°, 116.5(6)°, and 173.7(9)°. Structural correlations with other TeX3+ species have yielded an estimate of the electronegativity of the N3− group to be 3.1 ± 0.1. Keywords: tetratellurium (2+) cation, triazidotellurium(IV) cation, electronegativity, azide.

The title compound has been prepared in two different ways: First, by boiling single crystals of [(C2H5)4N]HgCl3 in a mixture of n-hexane/n-octane [4:1] at T = 350 K, and second, in a synthesis from stoichiometric quantities of the components. X-ray structure analysis gave the stoichiometry [(C2H5)4N]2Hg3Cl8, monoclinic, space group P21, a = 7.538(3), b = 19.909(6), c = 10.274(3) Å, β = 95.13(1)°, V = 1535.7(9) A3, Z = 2. The basic [Hg3Cl8]2--units form broken zig-zag chains along [100]. The Hg–Cl distances within the [Hg3Cl8]2- clusters range from 2.315(3) to 2.755(4) Å. This is a new coordination type for halomercurates.

Single crystals of the compound α -Zn3(BO3)(PO4) were obtained at 1050 °C by using B2O3, P2O5 and ZnCO3 as starting materials and subsequent cooling to 600°C with 20°C/h. X-ray investigations on single crystals yield a new crystal structure in the monoclinic space group Cm - (Nr. 8) with a = 972.5(2); b = 1272.0(3); c = 487.4(3) pm; β = 119.80 (4)°; Z = 4. The structure contains isolated trigonally planar BO3 and tetrahedral PO4 units which are not joined together. Zinc occupies three crystallographically different point positions and is trigonal-bipyramidally, tetragonal-pyramidally or distorted tetrahedrally coordinated by oxygen

Transparent single crystals of Na4Ga2S5 were obtained from a melt of Na2S, Ga and S. Na4Ga2S5 is monoclinic, space group P21/c with a = 7.967(1), b = 6.133(2), c = 19.852(9) Å, β = 91.61(2)°, Ζ = 4. Its crystal structure was refined to a conventional R of 0.033 for 1150 observed reflections.The structure of Na4Ga2S5 is of a new type. It is characterized by infinite ribbon like thiogallate anions, -, which are built up by GaS4-tetrahedra (mean Ga-S bond length 2.28 A) sharing apices and edges. The four crystallographically independent alkali cations are coordinated to six sulphur atoms in distorted octahedral configurations.

Abstract This study is about the synthesis of N,N′-bis(4-chlorophenyl)thiourea N,N-dimethylformamide (C16H17Cl2N3OS) compound. Single crystals of the compound were obtained by slow evaporation of N,N′-bis(4-chlorophenyl)thiourea (C13H10Cl2N2S) in N,N-dimethylformamide (C3H7NO; DMF) through recrystallization under mild condition. Important classical N–H⋯O links the two molecules together. Results revealed that C16H17Cl2N3OS crystallized in the monoclinic space group P21/c with the respective cell parameters of a = 92,360 (4) Å, b = 7.2232 (3) Å, 25.2555 (11) Å, β = 91.376 (3), α = γ = 90°, V = 1684.40 (12) Å3, T = 119.94 (13) K and Z = 4 and Z′ = 1.
