“…Whilst the overall shapes of these new Cu 10 to Cu 12 cluster vary considerably, they all have a similar Cu 4 C 4 core ( Figure 1) defined by bridges from the terminal alkynyl carbon atoms. A similar structural motif was first reported [12] for a copper alkyl complex, [Cu 4 A C H T U N G T R E N N U N G (Me 3 SiCH 2 ) 4 ], with a square arrangement of Cu atoms (Cu À Cu 2.42 ). Each alkyl ligand forms three-centre two electron (3c-2e) bonds with two copper atoms resulting in C-Cu-C angles of 1648 and a "pinching in" of the Cu atoms on the sides of the C 4 square.…”

The facile syntheses and the structures of five new Cu(I) alkynyl clusters, [Cu(12)(hfac)(8)(C[triple chemical bond]CnPr)(4)(thf)(6)]xTHF (1), [Cu(12)(hfac)(8)(C[triple chemical bond]CtBu)(4)] (2), [Cu(12)(hfac)(8)(C[triple chemical bond]CSiMe(3))(4)] (3), [Cu(10)(hfac)(6)(C[triple chemical bond]CtBu)(4)(diethyl ether)]/[Cu(10)(hfac)(6)(C[triple chemical bond]CtBu)(3)(C[triple chemical bond]CnPr)(diethyl ether)] (4) and [Cu(10)(hfac)(6)(C[triple chemical bond]CtBu)(4)(diethyl ether)] (5) are reported, in which hfacH=1,1,1,5,5,5-hexafluoropentan-2,4-dione. The first independent molecule found in the crystals of 4 (4 a) proved to be chemically identical to 5. The Cu(10) and Cu(12) cores in these clusters are based on a central "square" Cu(4)C(4) unit. Whilst the connectivities of the Cu(10) or Cu(12) units remain identical the geometries vary considerably and depend on the bulk of the alkynyl group, weak coordination of ether molecules to copper atoms in the core and CuO intramolecular contacts formed between Cu-hfac units on the periphery of the cluster. Similar intermolecular contacts and interlocking of Cu-hfac units are formed in the simple model complex [Cu(2)(hfac)(2)(HC[triple chemical bond]CtBu)] (6). When linear alkynes, C(n)H(2n+1)C[triple chemical bond]CH, are used in the synthesis and non-coordinating solvents are used in the workup, further association of the Cu(4)C(4) cores occurs and clusters with more than eighteen copper atoms are isolated.

“…[241][242][243] Bei der Suche nach neuen Materialien wurde eine Serie von Au-Cu-Alkinylkomplexen ausgehend von [(Ph 3 P)AuCCR] (R = organische oder metallorganische Gruppe) synthetisiert. Die strukturelle Charakterisierung ergab, dass die Alkinylliganden durch s-Bindungen an das Au I -Zentrum und durch p-Bindungen an das Cu I -Zentrum gebunden sind.…”

Metallalkinylkomplexe bergen eine große Anziehungskraft für die Synthesechemie, die Strukturchemie und die Materialwissenschaften, sodass mittlerweile eine Vielzahl von Reaktionen zur M‐CC‐Verknüpfung mit einer ganzen Skala von Übergangsmetall‐ und Alkinylreagentien entwickelt wurde. Einige Methoden sind breit anwendbar, andere beschränken sich auf ein spezielles Metall oder Substrat. Wegen der linearen Geometrie der Alkinyleinheit und ihrem ungesättigten Charakter sind die Metallalkinyle attraktive Bausteine für molekulare Drähte und polymere metallorganische Materialien, die interessante physikalische Eigenschaften wie flüssigkristallines Verhalten, optische Nichtlinearität, Lumineszenz und elektrische Leitfähigkeit aufweisen können. Dieses einzigartige Spektrum an Eigenschaften steht als treibende Kraft hinter der intensiven Erforschung von Metall‐Alkinyl‐σ‐Komplexen. Die Entwicklung und Fortschritte insbesondere der letzten zehn Jahre werden in diesem Aufsatz zusammengefasst.

“…In a complex where two or more ligands of the same type are bonded with a metal ion is called a binary ligand complexes and if the different types of ligand are present, then the complexes is said to be ternary complexes or mixed ligands complex 6 . It is now generally agreed that in a solution containing metal ions and two different suitable ligands are usually combined.…”

Transition metal form complex with ligand and this metal complexes play very important roles in biological system. Metal complexes is a branch of biological inorganic chemistry. This field has important implications in many other sciences, ranging form medicine to the environment. It is an interdisciplinary science. Scientists working in different areas of Chemistry, Biochemistry, Biology, Physiology, Agriculture, Physics and even Mathematics. Furthermore, studies of the roles of metal ions is biological system often involve development of relevant chemistry. The analysis of the representative species distribution curves shows that in the pH range 1-4 metal ion M(II) is the major species. In the pH range 4-7 for Cu(II) complex or above in case of Ni(II) complexes the species MA, ML, MAL exist, where M = Ni(II), Cu(II) and A = Diethylenetriamine (DET) and L = Oxalic acid, Tyrosin, Ethylenediamine, Glycine, alpha-Alaline, Phenylalanine, The percentage of the species MA 2 , ML 2 are very less. In the present study, the ligand A, are characterized by three p values. p 1 and p 2 corresponds to two -NH 2 protons and p 3 corrosponds to -NH proton. It is observed that for the metal ligand formation constant logK 1 and logK 2 , the difference (logK 1 -logK 2 ) is more in case of Cu(II) as compare to Ni(II). The logK value was calculated by using SCOGS computer program. The value of logK are more negative of Cu(II) complex compair to Ni(II) complex. So, the complex of Ni(II) is more stable than Cu(II) complexes.
