benzothieno[3,2-b]benzoheteroles containingGroup 15 (N, P, As, and Sb) and Group 16 (O, S, Se, and Te) elements were synthesized by a versatile method. X-ray analyses revealed that all the tetracyclic heteroacene skeletons were planar. A linear relationship was found between the excitation energies of Group 16-heteroacenes and their atomic radius, in contrast to Group 15-heteroacenes. Density functional

Synthesis, Structures, and Some Reactions of [(Thioacyl)thio]- and (Acylseleno)antimony and -bismuth Derivatives ((RCSS)xMR and (RCOSe)xMR with M = Sb, Bi andx = 1–3)
Despite the large atomic radii, the CS ⋅⋅⋅ Sb distances in (RCSS)2MR1 (M = As, Sb, Bi; R1 = aryl) and the CO ⋅⋅⋅ Sb distances in (RCOS)xMR (M = As, Sb, Bi; x = 2, 3) are comparable to or shorter than those of the corresponding arsenicderivatives (Tables 2 and 3). A molecular-orbital calculation performed on the model compounds (MeC(E)E1)3−xMMex (M = As, Sb, Bi; E = O, S; E1 = S, Se; x = 1, 2) at the

Synthesis of 1-Stibaphenalenes, the First Example of Group 15 Phenalenes, via a 1,5-Dilithium Intermediate
The first examples of 1-stibaphenalenes 1 and 6 have been prepared by the condensation of dibromophenylstibane with 1,5-dilithium intermediate 5, generated in situ from (Z)-1-bromo-2-[1-(8-bromonaphthyl)]-1-trimethylsilylethene (4). Single crystal X-ray analysis of 1 revealed that the naphthalene and the fused stibinine ring are almost coplanar (mean deviation 0.0264 Å), and the phenyl group on the antimony is oriented perpendicular with the phenalene ring.

Complex formation between SbPhX2, SbPh2X and SbPh2X3, where XCl or Br, and the nitrogendonors pyridine, 2,2′-bipyridine and 1,10-phenanthroline is described. With monophenylantimony(III) halides, pyridine gives complexes containing one and two molecules of pyridine, but only 1:1 compounds are obtained with the diphenyl monohalides. 2,2′-Bipyridine and 1, 10-phenanthroline give 1:1 complexes with both
描述了SbPhX 2,SbPh 2 X和SbPh 2 X 3(其中XCl或Br)与氮供体吡啶,2,2'-联吡啶和1,10-菲咯啉之间的络合物形成。与一苯基锑(III)卤化物一起,吡啶得到的复合物含有一个和两个吡啶分子,但是与二苯基一卤化物只得到1:1的化合物。2,2'-联吡啶和1,10-菲咯啉与单和二苯基卤化物形成1:1的配合物,并且已确定SbPhCl 2 ·bpy的结构。吡啶可产生1:1的SbPh 2 X 3化合物对于XBr或Cl,而三溴二苯锑和2,2'联吡啶和1,10-菲咯啉可形成1:2的配合物。在1,10-菲咯啉和三氯化二苯锑之间也获得了稳定的1:2络合物,但是带有2,2'-联吡啶的初始产物显然水解不稳定,结晶时得到bpyH [SbPh 2 Cl 4 ]。该化合物的结构也已获得。
