Structural Aspects of Chlorine‐Aluminium Alkoxides 

01-Jul-2011 | Michael Veith; Hameed Ullah Wazir; Tatjana Kirs; Volker Huch; Michael Zimmer, Zeitschrift für anorganische und allgemeine Chemie, 2011

Abstract LiAlH4 and AlCl3 reacted in a ratio 1:3 to obtain Cl2AlH, which is stabilised by the addition of two equivalents of N-methylpiperidine (nmp) to form dichloroalane (1) as bis adduct of nmp. Compound 1 was allowed to react with 2,6-tBu-4-MeC6H2OH and HOcHex in a 1:1 ratio to get ...

Synthesis of (Ge9–Ge9)6– Dimeric Zintl Ions in Liquid Ammonia Solutions of K4Ge9: Low‐Dimensional Coordination Networks in the Crystal Structure of the Ammoniates Kn[K([2.2.2]crypt)]6–n[Ge9–Ge9](NH3)m (n = 2, 3, and 4) 

01-Jul-2011 | Sandra Scharfe; Thomas F. Fässler, Zeitschrift für anorganische und allgemeine Chemie, 2011

Abstract Three new compounds of the dimeric cluster anion [Ge9–Ge9]6– were obtained from liquid ammonia solutions of the Zintl phase K4Ge9. All of them follow the general formula Kn[K([2.2.2]crypt)]6–n[Ge9–Ge9](NH3)m (1: n = 4, m = 14; 2: n = 3, m = 18; 3: n = 2, m = 17.28) and comprise ...

Vibrational Spectra and Quantum Chemical Calculations of the Pure and Mixed Cluster Anions [SixGe4–x]4– and [GexSn4–x]4– (x = 0–4) in Compounds with Potassium and Cesium 

01-Jul-2011 | Ormeci, Alim; Aydemir, Umut; Somer, Mehmet, Zeitschrift für anorganische und allgemeine Chemie, 2011

Abstract The Raman spectroscopic studies on samples with the starting compositions Cs4[Si2Ge2] and M4[Ge2Sn2] (M = K, Cs) verify unambiguously the presence of phases composed of the mixed cluster moieties [SixGe4–x]4– and [GexSn4–x]4– (x = 1–3) including the pure anions [E4]4– (E = Si, Ge, Sn). ...

Anatomy of Thought, Mechanism, and Mathematics 

01-Jul-2011 | Andersson, Sten, Zeitschrift für anorganische und allgemeine Chemie, 2011

Abstract The organizations of neurons, axons and dendrites in brain space are described with structures of infinite types of rods using Gauss distribution mathematics. Hermitian wavelets are used to describe mechanisms of thought.

Mononuclear Complexes of Iron(II) Based on Symmetrical Tripodand Ligands: Novel Parent Systems for the Development of New Spin Crossover Metallomesogens 

01-Jul-2011 | Maksym Seredyuk; Ana B. Gaspar; Joachim Kusz; Philipp Gütlich, Zeitschrift für anorganische und allgemeine Chemie, 2011

Abstract The synthesis and characterization of a series of mononuclear tripodand-based FeII complexes by means of Mössbauer andUV/Vis spectroscopic as well as magnetic methods is reported. The complexes were obtained from the reactions of FeII salt with heterocyclic aldehydes (imd = ...

Chiral Heterobimetallic Gold(I) Ferrocenyldithiophosphonato Complexes 

01-Jul-2011 | Karakus, Mehmet; Lönnecke, Peter; Hildebrand, Mike; Hey‐Hawkins, Evamarie, Zeitschrift für anorganische und allgemeine Chemie, 2011

Abstract Chiral and non-chiral ferrocenyldithiophosphonates [tBuNH3][Fe(η5-C5H5){η5-C5H4P(OR)S2}] were prepared from [Fe(η5-C5H5){η5-C5H4PS(μ-S)}]2 and the respective alcohol ROH [R = bornyl (1), myrtenyl (2), adamantyl (3)] and tBuNH2 as base. The reaction with [AuCl(tht)] (tht = ...

Synthesis, Crystal and Electronic Structure of [K[18]crown‐6)]2[Sn2Bi2] 

01-Jul-2011 | Felicitas Lips; Marc Raupach; Werner Massa; Stefanie Dehnen, Zeitschrift für anorganische und allgemeine Chemie, 2011

Abstract Extraction of an alloy of the nominal composition “KSnBi” by an [18]crown-6 melt, and subsequent by 1,2-diaminoethane (en) resulted in the formation of a new ternary Zintl salt [K([18]crown-6)]2[Sn2Bi2] (1) comprising the known binary anion [Sn2Bi2]2–. Herein we report synthesis and ...

Copper(I) Chelation by Tetradentate NSSN Donor Ligands: Reversible Oxidation but no Oxygenation 

01-Jul-2011 | Johannes Schnödt; Monika Sieger; Biprajit Sarkar; Jan Fiedler; Jorge S. Manzur; Cheng-Yong Su; Wolfgang Kaim; Cheng‐ ..., Zeitschrift für anorganische und allgemeine Chemie, 2011

Abstract The copper(I) complexes [Cu(L4)](ClO4), L4 = 1,6-bis(N-methyl-1H-benzimidazol-2-yl)-2,5-dithiahexane (bmbdh) or 1,7-bis(N-methyl-1H-benzimidazol-2-yl)-2,6-dithiaheptane (bmdhp) were obtained and investigated through structure analysis (bmdhp compounds), cyclic voltammetry, UV/Vis/NIR ...
