A Straightforward Synthesis of Diverse Nickel Dithiolene Complexes Appended with Hydrogen-Bond Donor/Acceptor Groups
摘要:
Nickel dithiolene complexes symmetrically appended with hydrogen-bond donor/acceptor functionalities such as imide, amide, or cyano/ amide groups have been synthesized by a straightforward method of wide applicability starting from one single precursor. Single-crystal X-ray structures reveal the occurrence of one type of ribbon common to all compounds that is based on a recurrent self-complementary intermolecular hydrogen-bonded ring motif linking the symmetrically substituted complexes.
Synthesis and X-ray structure of [Ni<sub>16</sub>(CO)<sub>23</sub>C<sub>4</sub>]<sup>4–</sup>: a tetracarbide anionic cluster containing two interstitial C<sub>2</sub>fragments
Reaction of [Ni10(CO)16C2]2â with four equivalents of PPh3 in tetrahydrofuran quantitatively afforded the novel brown [Ni16(CO)23C4]4â tetra-anion, whose metal frame has been shown by X-ray diffraction studies to consist of a unique hexadecanuclear truncated ν2-octahedron caging two interstitial C2 moieties with a very short interatomic C-C separation of 1.38 à .

The synthesis and properties of the new dicarbidocarbonyl bimetallic clusters [Co3Ni7(CO)16C2]2− (I), [Co3Ni7(CO)16C2]3− (II), and [Co3Ni7(CO)15C2]3− (III), are described. Compound I, which is paramagnetic, has been synthesized in high yields by redox-condensation of Co3(CO)9CCl with [Ni9(CO)17C]2−, whereas the diamagnetic trianions II and III have been respectively obtained by reduction of I, with
新的二碳羰基羰基双金属簇[Co 3 Ni 7(CO)16 C 2 ] 2-(I),[Co 3 Ni 7(CO)16 C 2 ] 3-(II)和[Co 3描述了Ni 7(CO)15 C 2 ] 3-(III)。顺磁性化合物I是通过Co 3(CO)9 CCl与[Ni 9(CO)17 C] 2-的氧化还原缩合反应高收率合成的,而抗磁性三阴离子II和III分别是通过将I还原,用THF中的金属钠和甲醇中的氢氧化钠还原得到的。阴离子I已与几种四取代的铵或phospho阳离子缔合以结晶状态分离,其特征在于对四苯基phosph盐进行了元素分析和单晶X射线衍射研究。

Reaction of [Ru(II)(PPh(3))(3)Cl(2)] with HQ and KCN produces a new dicyanoruthenium(III) building block, [Ru(III)(Q)(2)(CN)(2)](-). It reacts with hydrated CoCl(2) in MeOH or DMF to produce a trinuclear compound 2 or a 1-D zigzag chain 3.
