Octadecabromidobis(dicarbido)decadysprosium, [Dy10Br18(C2)2]

K. Daub and G. Meyer

Abstract top

Single crystals of [Dy10Br18(C2)2] were obtained during the reaction of DyBr3 with dysprosium metal and graphite in a sealed tantalum container. In the crystal structure, the Dy atoms form dimers of edge-sharing octahedra, each encapsulating a C2 unit. The metal atoms are surrounded by Br atoms above the cluster edges and vertices, respectively. The dimers are connected to each other by Br atoms, leading to a three-dimensional network. [Dy10Br18(C2)2] is isotypic with its iodido analogue [Dy10I18(C2)2].

Comment top

A number of ternary and quaternary halides of the general formulae [{RE10(C2)2}Xn] with RE = Gd, Tb, Er, Y; X = Cl, Br, I; n = 17–19 and Ax[{RE10(C2)2}Xn] with A = K, Rb, Cs; x = 1–3; n = 18–21 have been observed and were compiled by Meyer and Wickleder (2000). Among these halides, three bromides with the formula [{RE10(C2)2}Br18], where RE is Gd, Tb, and Er, are known and were structurally studied by Lie\&s (1996), Mattausch et al. (2002) and Uhrlandt et al. (1994).

The crystal structure of the title compound is isotypic with the iodide analogue [{Dy10(C2)2}I18] studied recently by Mattausch et al. (2007). As many reduced rare earth halides, the cluster compound [{Dy10(C2)2}Br18] consists of an octahedral arrangement of dysprosium atoms stabilized by an interstitial C2 dumbbell. The dysprosium octahedra are connected via common edges leading to the formation of dimers. The cluster cores are surrounded by bromine atoms above the cluster edges and vertices, respectively (Fig. 1). Some of the bromine atoms belong to a single dimeric unit while others connect neighbouring dimers, thus leading to a three-dimensional network (Fig. 2). Due to the slight elongation of the dysprosium octahedra established roughly parallel to the axis of the C2 units, the Dy—Dy distances range from 3.1832 (11) to 4.0369 (9) Å. The Dy—Br distances in [{Dy10(C2)2}Br18] vary between 2.7157 (15) and 3.3231 (12) Å with the distances to the edge-bridging bromine atoms that are placed between two condensed octahedra significantly larger than those to the other ligands. The C—C bond length is 1.437 (13) Å.

Related literature top

Details of ternary and quaternary halides of the rare earth elements have been compiled by Meyer & Wickleder (2000). Bromides with the formula [RE10Br18(C2)2], where RE is Gd, Tb and Er, have been studied by Lie\&s (1996), Mattausch et al. (2002) and Uhrlandt et al. (1994). Recently, the first dysprosium compound, [Dy10I18(C2)2], belonging to this structural family, was reported by Mattausch et al. (2007). [Dy10Br18(C2)2] is obtained by reduction of DyBr3 with dysprosium and graphite. For the synthesis of the starting material DyBr3, see Meyer et al. (1987).

Experimental top

Black parallelepipedic crystals of [{Dy10(C2)2}Br18] were obtained by the reaction of DyBr3 (150 mg) with dysprosium powder (85 mg, Chempur, 99,9%) and graphite (8 mg, Merck, p.a.) in a tantalum container at 1273 K. DyBr3 had been synthesized previously according to the ammonium bromide route (Meyer et al., 1987), followed by sublimation in high vacuum for purification. Due to air and moisture sensitivity of both reagents and products, all handlings were carried out in an argon-filled glove box (M. Braun, Garching, Germany).

Refinement top

The highest peak in the final difference Fourier map is 0.99 Å from atom Dy4 and the deepest hole is 0.88 Å from the same atom.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
