Abstract Single crystals of the new compound Ba2KZn3(B3O6)(B6O13) were obtained by using a B2O3 flux technique; they crystallize in an as yet unknown structure type. X-ray investigations led to the space group Ci1-P1̄ (Nr.2) with lattice parameters a = 705.2(2), b = 712.5(2), c = 1880.3(6), a = 93.43(3)°, β = 90.72(2)°, γ = 119.57(2)°, Z = 2. The structure contains (B3O6)3--rings and a new discrete (B6O13)8- anion, which is composed of two BO4 and two B2O5 units. Zn2+ is tetrahedrally coordinated by oxygen and two out of three tenfold coordinated Ba-sites are statistically occupied by Ba2+ and K+.

Single crystals of the compounds MnFe(BO3)O (I) and MnAl0.5Y0.5(BO3)O (II), were obtained by a B2O3 flux technique. I crystallizes with orthorhombic symmetry, space group D162h -Pnma (Nr.62), a = 939.92; b = 319.41; c = 939.11 pm; Z = 4 and II with monoclinic symmetry, space group C52h-P21/n (Nr. 14). a = 325.6; b = 955.1; c = 929.2 pm; β = 90.70° ; Z = 4. I is isotypic to the mineral Warwickite, while II is a distorded variant of this structure. All metal ions are octahedrally coordinated. Both structures contain isolated, trigonal planar BO3 units and oxygen atoms that are not coordinated to boron.

Blue single crystals of Cu[μ3-O3P(CH2)2COOH].2H2O (1) and Cu[(RS)-μ3-O3PCH(C2H5)COOH].3H2O (2) have been prepared in aqueous Cu2+-solutions (pH = 2.5–3.5) containing 3-phosphonopropionic acid (1) and (RS)-2-phosphonobutyric acid (2), respectively. 1: Space group Pbca (no. 61) with a = 812.5(2), b = 919.00(9), c = 2102.3(2) pm. Cu2+ is five-fold coordinated by three oxygen atomsstemming from [O3P(CH2)2COOH]2– anions and two water molecules. The Cu-O bond lengths range from194.0(3) to 231.8(4) pm. The connection between the [O3P(CH2)2COOH]2– anions and the Cu2+ cations yields apolymeric structure with layers parallel to (001). The layers are linked by hydrogen bonds. 2: Space group Pbca(no. 61) with a = 1007.17(14), b = 961.2(3), c = 2180.9(4) pm. The copper cations are surrounded by five oxygen atoms in a square pyramidal fashion with Cu-O bonds between 193.6(4) and 236.9(4) pm. The coordination between [O3PCH(C2H5)COOH]2- and Cu2+ results in infinite puckered layers parallel to (001). The layers are not connected by any hydrogen bonds. Each layer contains both R and S isomers of the [O3PCH(C2H5)COOH]2-dianion. Water molecules not bound to Cu2+ are intercalated between the layers.UV/Vis spectra suggest three d-d transition bands at 743, 892, 1016 nm for 1 and four bands at 741, 838, 957and 1151 nm for 2, respectively. Magnetic measurements suggest a weak antiferromagnetic coupling betweenCu2+ due to a super-superexchange interaction. Thermoanalytical investigations in air show that the compounds are stable up to 95 °C (1) and 65 °C (2), respectively.

Single crystals of sodium copper(II) indium bis[phosphate(V)], NaCuIn(PO4)2, were grown from the melt under atmospheric conditions. The title phosphate crystallizes in the space group P21/n and is isotypic with KCuFe(PO4)2. In the crystal, two [CuO5] trigonal bipyramids share an edge to form a dimer [Cu2O8] that is connected to two PO4 tetrahedra. The obtained [Cu2P2O12] units are interconnected through vertices to form sheets that are sandwiched between undulating layers resulting from the junction of PO4 tetrahedra and [InO6] octahedra. The two types of layers are alternately stacked along [101] and are joined into a three-dimensional framework through vertex- and edge-sharing, leaving channels parallel to the stacking direction. The channels host the sodium cations that are surrounded by four oxygen atoms in form of a distorted disphenoid.

Abstract Single crystals of KBaCuV2O7Cl have been prepared by a flux technique and investigated by X-ray analysis. The compound crystallizes with tetragonal symmetry, space group C24v-P4 bm, a = 8.8581, c = 5.4711 Å, Z = 2. The crystal structure shows Cu2+ within a one sided strongly distorted CuO4Cl2 octahedron. The copper ion is shifted towards the nearer Cl- neighbour to form a CuO4Cl square pyramid. Two VO4 tetrahedra are connected to give stretched V2O7 double tetrahedra, and linked in planes via the oxygen corners of the CuO4Cl pyramids. The crystal structure and the structure of the complex BaO8Cl2 polyhedron are discussed.

Colorless and transparent single crystals of Ba2H3I were obtained by reacting Ba with dried and sublimed NH4I in a 4 : 1 molar ratio in silica-jacketed Nb ampoules at 1100 K for 13 h. The crystal structure of the title compound was determined and refined by means of single-crystal X-ray diffraction. Ba2H3I crystallizes in a stuffed anti-CdI2 structure isotypic to Sr2H3I in the space group P3̄m1 (no. 164) with the lattice parameters a = 451.86(12) and c = 811.84(23) pm. The structural results for Ba2H3I are consistent with bond lengths and coordination geometries of related binary and ternary hydrides

ABSTRACTWe have successfully synthesized single crystals of C60 fullerene complex with a symmetrical triplet donor of 2,3,6,7,10,11-hexamethoxytriphenylene (HMT). All spectroscopie data and analyses support the chemical composition of this complex as C60(HMT)2. Single crystals of C60(HMT)2 are, at 20±1 °C, cubic, space group Fd3c-Oh8 (No. 228) with a = 30.251(9) Å, α = 90.00°, V = 27682(30) Å3, Z = 16 (dcalcd = 1.476 gcm-3), and Ru (unweighted) = 0.098.

Single crystals of the new compounds Zn5Mn(BO3)2O4 (A ) and ZnFe(BO3)O (B) were prepared by using a B2O3 flux technique. Zn5Mn(BO3)2O4 is isostructural with Ni5Ti(BO3)2O4 and ZnFe(BO3)O is isotypic with the mineral warwickite. X-ray investigations on single crystals led to (A ) space group D92h -Pbam, a = 926.41(10), b = 1236.67(8), c = 304.55(3) pm, Z = 2, and (B) space group D162h-Pnma, a = 924.62(4), b = 314.1(10), c = 935.3(2) pm, Z = 4. The structure of Zn5Mn(BO3)2O4 (A ) contains four octahedrally coordinated metal sites, one of these statistically occupied by Zn2+ and Mn4+. In the structure of ZnFe(BO3)O the ions Zn2+ and Fe3+ occupy statistically both distorted octahedral sites. Both structures contain isolated BO3 units and oxygen that is not coordinated to boron.

Colourless single crystals of [Eu(CH3COO)2(H2O)3]Cl are obtained at about 5°C from a solution of EuCl3 · 6 H2O in a mixture of acetone, tetrahydrofurane and acetanhydride (1:1:2) to which a small amount of water had been added. [Eu(CH3COO)2(H2O)3]Cl crystallizes in the monoclinic system, space group P21/n (No. 14), a = 786.19(5), b = 791.86(5), c = 1768.81(13) pm; β = 98.235(6)°, R = 0.025, Rw = 0.021, Z = 4. Eu3+ is in nine-coordinate surrounding of O2-, three of which belong to water molecules and six to acetate anions (two bidentate and two monodentate). Cationic chains of the composition [Eu(CH3COO)2(H2O)3]+ are formed through further connection via acetate-oxygen atoms. These chains are stacked hexagonally parallel [100] and held together by “lonesome” Cl- anions. The chloride ions are surrounded by 4+1 aquo ligands.
