Heterobimetallic aggregates of copper(I) with thio-tungstate and -molybdate. Cation effect in aggregation of MS₄Cu₄Cl₄units, a crystallographic study

Heterothiometallic polymeric clusters

“…The square block m11 is connected via two 2 -Br ligands at two diagonal Cu atoms to form a one-dimensional polymer [PPh 4 ] 2 [MoS 4 (CuBr) 4 ]·Me 2 CO c7 [23], which can be regarded as an extended motif of o7. The pentanuclear cubane m12 (with an additional face) has two polymerization options along the extending direction of the additional face: head to head, such as {[NPr 4 ] 2 [WS 4 (CuCl) 4 ]} n ) and [Cu 4 Cl 2 BIPy 2 WS 4 ] n c8 [24], or head to tail, such as [(PPh 4 ) 2 (ReS 4 )Cu 4 I 5 ] n c9 [25].…”

Solid state synthesis of copper(I) thiotungstate cluster compounds at low heating temperatures. Crystal structures of [(n-Bu)4N]3-[WS4Cu3Cl3Br] and [Et4N]4[WS4Cu4I6]

“…(Found: C,20.7;H,4.3;N,3.3;W,9.4;Cu,13.6;C32H8oCu416N4S4W calcd. : C,20.8;H,4.4;N,3. methods. Several atoms were located from an E map; the remaining atoms were found during iterations of leastsquares refinement cycles and difference Fourier maps.…”

Generating Structural Motifs between Three-Dimensional Solids and Discrete Species Based on the {CuNCS} Unit: (PPh4)[(ReS4)Cu2(NCS)2], (NEt4)2[(ReS4)Cu3(NCS)4], and (PPh4)2[(ReS4)2Cu2(NCS)2]

“…In this context it is interesting to note that the colourless modification of crystalline CuNCS consists of mutually interlinked linear formations of (7) (6) 10.551 (4) 10.901 (3) 11.142 (4) 14.849 (6) 10.981 (3) c [] 12.860 (5) 22.782 (11) 12.296(3) a [8] 109.20(2) b [8] 90.66 (3) 92.35 (4) 96.40(2) g [8] 98. 17(2) V [ 3 ] 3079 (2) 3566 (3) 1356 (1) …”
