Millimeter-sized single crystals of Ln(6)M(4)Al(43) (Ln = Gd, Yb; M=Cr, Mo, W) were successfully grown with a molten aluminum flux. Synthetic conditions and physical properties for single crystals of all six analogs are discussed. The compounds exhibit metallic resistivity with room temperature values between 0.1 and 0.6 m Omega-cm. The Yb analogs are Pauli paramagnets with the Yb ion adopting the nonmagnetic divalent configuration (Yb2+). Gd6Cr4Al43, Gd6Mo4Al43, and Gd6W4Al43 appear to order antiferromagnetically at 19, 15, and 15 K, respectively.
