The First Neutral Adamantanoid Iron(III)-chelate Complex: Spontaneous Formation, Structure, and Electrochemistry
(1993)
Metalloautism - this term perfectly describes the characteristic of the adamantanoid iron(III) chelate complex 1 that the four iron centers do not interact with each other either electronically or magnetically. The four ...

Synthesis and Structure of the First Organometallic Galloxane Hydroxide Mes6Ga6O4(OH)4
(1994)
Controlled hydrolysis of (mesityl)2GaOH leads to the first structurally characterized galloxane hydroxide 1, which crystallizes as [l(thf)4]-6THF. The framework of 1 consists of a distorted Ga6 octahedron whose faces are ...

Doubly Lithiated Oligosilanes : Synthesis and Structure of the First Vicinal Dilithiodisilane
(1992)
Reaction of cyclotrisilane 1 with lithium yields, depending on the reaction conditions, either the trisilane 2 lithiated at the terminal positions or the vicinal dilithiodisilane 3. These silanes are the first examples of ...

Synthesis and Structure of the Disilagermirane R2Ge(SiR2)2 and the Solvent-Separated Ion Pair [Li([12]crown-4)2][GeR3]; (R = SiMe3)
(1994)
The disilagermirane 1 is obtained in good yields from (Me3Si)3 SiLi(thf) and GeCl2. The germyllithium compound 2 was also prepared; its anion, the higher homologue of the p. starting material for 1, might prove to be a ...

Insertion of zinc into the cyclophosphazene skeleton: synthesis and structure of six-membered-ring complexes of zinc
(1993)
Cyclozincaphosphazenes have been synthesized by the reaction of the bis-silylated ligand HN[P(NMe2)2NSiMe3]2
(1) with ZnR2 (2) (R = N(SiMe&, Me, Et). These complexes have been characterized by IR, NMR, and mass
spectroscopy ...

A thiouracil-Ca2+ complex containing two tautomeric forms of the thiouracilyl anion: Synthesis and crystal structure of [(thiouracilyl)2Ca·2DMSO·H2O]2
(1993)
A DMp. solution of 2-thiouracil dissolves Ca(OH)2 to give [(thiouracilyl)2Ca·2DMSO·H2O]n (1), a solution of which will in turn dissolve solid PtCl2. 1 is dimeric (n=2) in the solid, and the presence of two tautomers of the ...
