 Title    Synthese  
 Abstract    von [LRe(CO) 3 ] + -Komplexen mit makrocyclischen Liganden Die Kristallstrukturen von 1,4,7-TriazacycIononan-tricarbonyl-rhenium(I)-thiocyanat und 1,4,7-Trithiacyclononan-tricarbonyl-rhenium(I) -bromid-hemihy drat Synthesis of [LRe(CO) 3 ]" Complexes with Macrocyclic Ligands The Crystal Structures of l,4,7-Triazacyclononane-tricarbonyl-rhenium(I) Thiocyanate and of l,4,7-Trithiacyclononane-tricarbonyl-rhenium(I) Bromide Hemihydrate The tridentate macrocyclic ligands 1,4,7-triazacyclononane, its thia analogue 1,4.7-trithia-cyclononane, l-oxa-4,7-diazacyclononane, and N,N',N"-trimethyl-l ,4,7-triazacyclononane react with Re(CO) 5 Br in dimethylformamide to yield colorless, air-stable [LRe(CO) 3 ]Br complexes (L = tridentate macrocycle). With Mn(CO) 5 Br only the cyclic amines react to af-ford yellow-orange [LMn(CO),]Br complexes whereas 1.4,7-trithiacyclononane does not give stable complexes of manganese. The crystal structures of [([9]aneN 3)Re(CO) 3 ](NCS) and [([9]aneS 3)Re(CO) 3 ]Br-1/2 H : 0 have been determined. The former crystallizes in the orthorhom-bic space group Pbca (a = 12/763(4), b = 12.662(5), c = 17.472(9) Ä; Z = 8); whereas the latter crystallizes in the monoclinic space group P2,/c (a = 9.444(1). b = 11.797(2), c = 28.095(3) Ä. ß = 90,86(1); Z = 8).

 Title    [l,4,2]Diazaphospholidine [l,4,2]Diazaphospholidines  
 Abstract    Bis(diethylamino)phosphanylacetylen reacts with N.N'-dimethyl thiourea to give 2-diethyl-amino-l,4-dimethyl-3-methylene-[l,4,2]diazaphospholidine-5-thion (2) besides the [1.3.4]thi-azaphospholidine (1). The latter compound is converted into 2 by heating. Reaction of 2 with various reagents yields other members of the title compound class. All new compounds are characterized by some reactions and their NMR and IR spectra. In addition, the results of an X-ray structure analysis of 2-diethylamino-l ,4-dimethyl-3-methylene-2-thioxo-[l ,4.2]diazaphos-pholidine-5-thion (5) are reported.

 Title    Synthese und Struktur des ersten dreigliedrigen Arsen—Phosphor—Platin-Ringes Synthesis and Structure of the First Three-Membered Ring Containing Arsenic, Phosphorus and Platinum  
 Abstract    -butylphenylphosphane reacts with CpFe(C,H4AsCl2) in the presence of DBU to yield CpFe[C5H4As=PC6H2(f-Bu)?l. The reaction of this arsaphosphene with (Ph3P)2PtC2H4 yields CpFe[C5H4As—P[C6H2(r-Bu)3]Pt(PPh3)2], a compound with a three-membered ring containing arsenic, phosphorus and platinum.
