“…The compound is isostructural with KTi 4 -Cl 11 32 in which infinite chains, [Ti 3 (µ 3 -Cl i )(µ 2 -Cl i ) 3 Cl a 5 Cl a-a 4/2 ] 1 ∞ built of Ti 3 Cl 13 cluster units, are linked by Ti(IV) to form sheets. The puckered layers in the structure of AVNb 3 C l1 appear to be similar to the wavelike nets found in ANb 4 Cl 11 (A ) Rb, Cs) 33,34 in which the [Nb 4 Cl 16 ] 6cluster units compose the layers according to the connectivity formula Nb 4 Cl i 6 Cl a 10/2. However, the cluster framework in the title phases consists of infinite chains made of Nb 3 Cl 4 -Cl a 5 Cl a 4/2 units.…”

The first quaternary vanadium niobium compounds containing triangular Nb(3) clusters corresponding to the general formula, AVNb(3)Cl(11) (A = K, Rb, Cs, Tl), have been prepared in sealed quartz tubes from stoichiometric amounts of ACl (A = K, Rb, Cs), or Tl metal, VCl(3), Nb powder, and NbCl(5) heated at 740 degrees C. The compounds crystallize in the orthorhombic space group Pnma (No. 62). The crystal structures of the Rb and Tl members were determined by single-crystal X-ray diffraction techniques. Crystal data: a = 12.771(3) A, b = 6.811(2) A, c = 17.183(3) A, V = 1494.6(1) A(3), and Z = 4 for A = Rb; and a = 12.698(5) A, b = 6.798(3) A, c = 17.145(10) A, V = 1480.0(13) A(3), and Z = 4 for A = Tl. The crystal structure of AVNb(3)Cl(11) consists of triangular Nb(3)Cl(13) clusters (Nb-Nb = 2.826 A) connected to each other via four outer ligands to form infinite chains along the b-axis. The chains are connected by vanadium atoms located in an octahedral environment to form puckered sheets. The A(+) counterions are located between adjacent sheets and coordinate to twelve chlorine ligands in anticubeoctahedral geometry. Electronic structure calculations show bonding orbitals similar to those in Nb(3)Cl(8). Magnetic susceptibility measurements show paramagnetic Curie Weiss behavior.

“…Whereas many compounds are known in the system A/Nb/Cl (A = alkali metal), only three compounds have been reported in the ternary system A/Nb/Br, namely CsNb 4 Br 11 [2], K 4 Nb 6 Br 18 [3], Rb 3 Nb 2 Br 9 [4]. RbNb 4 Br 11 , on which we report here, is isotypic with CsNb 4 Cl 11 , CsNb 4 Br 11 [2] and RbNb 4 Cl 11 [5]. Physical properties of these compounds are widely unexplored.…”

RbNb 4 Br 11 was obtained by a solid state reaction of niobium powder, NbBr 5 and RbBr in a sealed niobium tube at 500°C. It crystallizes in the orthorhombic space group Pmma with a = 1699.5(1), b = 726.7(1), c = 694.5(1) pm, V = 857.6(1)·10 6 pm 3 , Z = 2 and is isotypic with CsNb 4 Br 11 . Four niobium atoms build a cluster in the shape of a rhombus with bonding distances of 295 pm (Nb1-Nb2) and 304 pm (Nb2-Nb2), respectively. The structure consists of [{Nb 4 }Br 6 i Br 10/2 a-a ] -
