Three novel Cu‐capped Ge9 clusters were synthesized from K4Ge9 and phosphane‐stabilized copper(I) compounds CuCl(PR3) with R = isopropyl (iPr) or cyclohexyl (Cy). Reactions in N,N‐dimethylformamide (dmf) at ambient temperature resulted in the isolation of [Cu(η4‐Ge9)(PCy3)]3– as a [K([2.2]crypt)] salt ([2.2]crypt: 1,7,10,16‐tetraoxa‐4,13‐diazacyclooctadecane). From solutions of [Cu(η4‐Ge9)(PiPr3)]3– in liquid ammonia, the anion was isolated when the reaction mixture was stored at –70 °C. Under the same reaction conditions but at a temperature of –40 °C the cluster [Cu(η4‐Ge9)(η1‐Ge9)]7– crystallized in the presence of [2.2.2]crypt(4,7,13,16,21,24‐hexaoxa‐1,10‐diazabicyclo[8.8.8]hexacosan)or [2.2]crypt. The ligand‐free intermetalloid cluster [Cu(η4‐Ge9)(η1‐Ge9)]7– is a unique example in which two differently bonded Ge9 units are linked by a transition‐metal atom. This cluster complex remarkably demonstrates the ability of homoatomic polyanions to bind in different modes to the same transition‐metal atom. One Ge9 nido cluster binds to the copper atom by means of its open square face, whereas the second Ge9 nido cluster is coordinated through one lone pair as a two‐electron σ donor. The key role of the flexible electron‐donor properties of [Ge9]4– in the reaction path towards the formation of intermetalliod clusters is discussed.

“…The palladium precursors 1 thus fill 36.3 % of the elemental cell, which amounts to 45.3 % of the pore volume. Analogously, other typical metal organic precursors for metal deposition are absorbed unchanged, for example, [(h 5 -C 5 H 5 )Cu(PMe 3 )] (2) [8] and [(CH 3 )Au(PMe 3 )] (3) [9] As expected, size and form selectivity are very high. For example, with 2 which is only slightly more space demanding than 1 and 3 only two instead of four embedded molecules are found, even though then only 28 % of the pore volume is filled with precursor molecules 2.…”

Metal@MOF: Loading of Highly Porous Coordination Polymers Host Lattices by Metal Organic Chemical Vapor Deposition

et al. 2005

Standing out from the vast majority of metal organic coordination polymers is the class of highly porous basic zinc carboxylates developed by Yaghi and co-workers.[1] Its prototype is MOF-5 (MOF = metal organic framework), in which {Zn 4 O} building blocks are linked together by terephthalate bridges to form a zeolite-like, cubic framework.[2] The extremely high specific surface area [2] of up to 4500 m 2 g À1 and a pore volume of 0.69 cm 3 cm À3 (for MOF-177), which has not been surpassed by any other crystalline substance, and thermal stability (up to 350 8C) opens up fascinating perspectives for the supramolecular host-guest chemistry.[3] Applications for these materials in miniaturized fuel cells and convenient gas-storage devices (for H 2 , CH 4 ), as gas sensors and for gas separation, as catalyst materials, and also for molecular electronics are emerging. [4] A report on the quantitative inclusion of C 60 and large polycyclic dye molecules (e.g. Astrazon Orange R) into the cavities of MOF-177 single crystals attracted our attention. [5] Could these MOF host lattices also be suitable to efficiently and selectively absorb typical metal organic chemical vapor deposition (CVD) precursors, provided these were volatile (gas absorption) or very soluble in nonpolar hydrocarbons and had matching size and shape to fit into the cavity? The release of the metal atoms of the precursors imbedded in the

“…This type of structure is frequently reported for complexes of the general composition CuX(PR 3 ), e. g. for R = Ph, Me and t Bu [25 -28]. In contrast to this result, Werner et al suggested a dimeric molecule for CuCl(P i Pr 3 ) as it was found for CuCl(PCy 3 ) [24]. In [CuCl(P i Pr 3 )] 4 the Cu-P distance amounts to 2.1926(5)Å, and the Cu-Cl distances along the cube edge range from 2.3981(5) to 2.5282(5)Å.…”

The synthesis of several phosphine Cu(I) complexes is reported, and their reactivity towards the solvents ethylenediamine (en) and dimethylformamide (dmf) has been investigated. CuX(PPh 3 ) [X = Cl (1), Br (2)], CuCl(PCy 3 ) (3) and CuCl(P i Pr 3 ) n [n = 1 (4), 2 (5)] were prepared according to adapted literature procedures. The complexes CuCl(P i Pr 3 ) n were obtained in crystalline form from a hexane solution at −70 • C and structurally characterized for n = 1 and 2. Copper halide complexes of PCy 3 (3) and P i Pr 3 [n = 1 (4)] gave colorless solutions in both en and dmf indicating the absence of Cu(II) ions. CuCl(P i Pr 3 ) 2 is stable in dmf solutions. By contrast, the complexes CuX(PPh 3 ) (X = Cl, Br) dissolve with blue color in en and with greenish-yellow color in dmf at higher temperatures under inert gas indicating a redox process affording Cu(II). At room temperature colorless crystals of CuX(PPh 3 )(en) 2 [X = Cl (6), Br (7)] and CuX(PPh 3 )(dmf) [X = Cl (8), Br (9)] were isolated from the solutions and analyzed by single-crystal X-ray diffraction.
