inorganic compounds
Ytterbium indium rhodium tetracopper, YbIn1-xRhxCu4 [x = 0.19 (3)], an Rh-substituted version of the compound YbInCu4, has been synthesized from the correspondng elements using a Cu/In flux. Its structure is a substitutional derivative of the AuBe5 type (Pearson code cF24). All atoms occupy special positions: Yb (site symmetry 
3m), In/Rh (3m) and Cu (.3m). A greater Rh content in the solid solutions, although possible, could not be confirmed by structure analyses due to poor quality of the single crystals.

Special details top
Experimental. Data collection is performed with four batch runs at φ = 0.00 ° (450 frames), at φ = 90.00 ° (450 frames), at φ = 180.00 ° (450 frames), and at φ = 270.00 (450 frames). Frame width = 0.40 \& in ω. Data are merged, corrected for decay, and treated with multi-scan absorption corrections. |
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. |
