“…In addition it may be noted that N-coordination of the thiocyanate group probably arises from a fine interplay of electronic and steric effects associated both with the tmen and azide ligands coordinated to the copper atom. Finally, in agreement with the general aspects which have already found for coordinated azido [13, 1b] and thiocyanato [14] groups, both are essentially linear, N4AN5AN6 177.0(4)°and SAC1AN1 178.3(4)°. However, the NCS ligand is not quite co-linear with the copper atom since the angle CuAN1AC1 is 161.9(4)°.…”

The compounds [Cu(N 3 )(NSC)(tmen)] n (1), [Cu(N 3 )(NCO)(tmen)] n (2) and [Cu(N 3 )(NCO)(tmen)] 2 (3) (tmen ¼ N,N,N¢,N¢-tetramethylethylenediamine) were synthesized and studied by i.r. spectroscopy. Single crystals of compounds (1) and (3) were obtained and characterized by X-ray diffraction. The structure of compound (1) consists of neutral chains of copper(II) ions bridged by a single azido ligand showing the asymmetric end-to-end coordination fashion. Each copper ion is also surrounded by the other three nitrogen atoms; two from one N,N,N¢,N¢-tetramethylethylenediamine and one from a terminal bonded thiocyanate group. Compound (2) decomposes slowly in acetone and the product formed [Cu(N 3 )(NCO)(tmen)] 2 (3) crystallizes in the monoclinic system (P2 1 ). The structure of (3) consists of dimeric units in which the Cu atoms are penta-coordinated and connected by l(1,3) bridging azido and cyanate ligands. In both cases the five coordinated atoms give rise to a slightly distorted square-based pyramid coordination geometry at each copper ion. The thermal behavior of [Cu(N 3 )(NSC)(tmen)] n (1) and [Cu(N 3 )(NCO)(tmen)] n (2) were investigated and the final decomposition products were identified by X-ray powder diagrams.

“…The cyano group is almost linear (Cu-C1-N1 174.81 (2) ). The Cu-P distance is in good agreement with the average value of 2.25(4) Å (see Table II) established for Cu I -PPh 3 complexes [7,[15][16][17][18][19][20]. The N1-C1 bond length of 1.142(3) Å is close to that expected for a CN triple bond [21] and the Cu-C1 bond distance of 1.936(2) Å is in good agreement with literature data [21].…”

Electrosyntheses of cyano copper(I) complexes were carried out by galvanostatic dissolution of copper metal into an acetonitrile solution of malononitrile, used as starting material. Electrochemical reductive cleavage of malononitrile occurs, at the cathode, leading to the formation of cyanide. In the presence of different donors the complexes [Cu(CN)(PPh 3 ) 2 ] Á CH 3 CN (1) and [Cu(CN)(bipy)(PPh 3 )] (2) are obtained. The compounds were characterized analytically and the molecular structure of 2 was determined by single-crystal X-ray analysis. Crystals are triclinic and consist of monomeric molecules in which the copper atom has distorted tetrahedral geometry.

“…A structural motif of this kind with monodentate thiocyanate ion is also found in other phosphine-copper(I) complexes, bearing triphenylphosphine-phenanthroline [21], 4,6-dimethylpyrimidine-2(1H)-thione-S [22], bis(diphenylphosphino)methane (dppm) [23] and bis(diphenylphosphino)ethane (dppe) [24].…”
