Copper(I) complexes of 1,2-bis(diphenylphosphino)ethane (dppe) with a stoichiometry Cu2(dppe)3(X)2 [X – = CN- (1), SCN- (2), NO3- (3)] are obtained from direct reactions of CuX and dppe. The complexes are structurally and spectroscopically (NMR and IR) characterized. The structure of the [Cu2(dppe)3]2+ dication is similar to the structural motif observed in many other complexes with a chelating dppe and a bridging dppe connecting two copper centers. In complexes 1-3, the anions are confined to the cavity formed by the phosphines which force a monodentate coordination mode despite the predominant bidentate/bridging character of the anions. The coordination angles rather than the thermochemical radii dictate the steric requirement of anions. While the solution behavior of 3, with nitrate, is similar to complexes studied earlier, complexes with pseudohalides exhibit new solution behavior.

Line-imaging Raman spectroscopy provides a contiguous series of Raman spectra along a line in space. The resulting image provides a one-dimensional spatial profile containing information about the bonding and chemical environment being sampled. The instrument configuration described here has a spatial resolution of about 5 mum and a spectral resolution of approximately 10 cm-1. Two examples highlight the use of in situ line-imaging Raman spectroscopy in electrochemical engineering. In the first example, the cation transport and redox characteristics of a thin (? 36 nm) nickel hexacyanoferrate film are probed. The oxidation state of iron centers within the nickel hexacyanoferrate thin film is shown to be readily modulated between ferric and ferrous states in the freshly prepared film. However, repeated cycling results in an irreversible loss of capacity as the iron centers no longer are able to efficiently switch into the ferric state. In the second example, we demonstrate the simultaneous imaging of a thin film of semiconducting copper (I) thiocyanate and the electrolyte chemistry from which the film was deposited. We show that copper thiocyanate electrodeposits have the beta crystal form and the deposition involves a CuSCN+ precursor that forms via homogeneous solution phase chemistry upon addition of copper sulfate to a potassium thiocyanate containing electrolyte.

Treatment of [Et4N][Tp*WS3] (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) (1) with CuX (X = Br, SCN) and PPh3 or 1,1-bis(diphenylphosphino)methane (dppm) produced two neutral trinuclear clusters [Tp*W(mu3-S)(mu-S)2Cu 2Br(PPh3)] (2) and [Tp*W(mu3-S)(mu-S) 2Cu2(SCN)(dppm)]2·MeCN·Et 2O (3·MeCN·Et2O). Reactions of 1 with [Cu(MeCN)4]PF6, NH4PF6 and 1,3-bis(diphenylphosphino)propane (dppp), N,N-bi(diphenylphosphanylmethyl)-2- aminopyridine (bdppmapy), N,N,N?,N?-tetra(diphenylphosphanylmethyl) ethylenediamine (dppeda), or 1,4-N,N,N?,N?- tetra(diphenylphosphanylmethyl)benzenediamine (dpppda) afforded four clusters containing butterfly-shaped [Tp*WS3Cu2] cores, [Tp*W(mu3-S)(mu-S)2Cu2(dpppds)] (PF6)·1.25MeCN (dpppds = 1,3-bis(diphenylphosphino)propane disulfide) (4·1.25MeCN), [Tp*W(mu3-S)(mu-S) 2Cu2(bdppmapy)](PF6)·3MeCN (5·3MeCN) and {[Tp*W(mu3-S)(mu-S)2Cu 2]2(L)]}(PF6)2·Sol (6·Et2O: L = dppeda, Sol = Et2O; 7·1.25MeCN: L = dpppda, Sol = 1.25MeCN). Compounds 2-7 were characterized by elemental analysis, IR, UV-Vis, 1H and 31P{1H} NMR spectra, electrospray ion mass spectra (ESI-MS) and single-crystal X-ray diffraction. Compound 2 or 3 has a butterfly-shaped [Tp*WS 3Cu2] core in which one [Tp*WS3] unit binds two Cu(i) centers via one mu3-S and two mu-S atoms. In the cationic structure of 4 or 5, one in situ-formed dpppds or bdppmapy combines with the [Tp*WS3Cu2] core via each of its two S atoms or two P atoms coordinated at each Cu(i) center. In the bicationic structure of 6 or 7, two [Tp*WS3Cu2] cores are linked by one dppeda or dpppda bridge to form a bicyclic structure. The isolation of 2-7 with unstable [Tp*WS3Cu2] cores may be ascribed to the coordination of P- or S-donor ligands at Cu(i) centers of these cores. The third-order nonlinear optical (NLO) properties of 2-7 in DMF were also investigated by using the femtosecond degenerate four-wave mixing (DFWM) technique at 800 nm.
