u(I) complexes possess a broad range of applications in
catalysis, photo-luminescent materials and in biological
sciences. In this regard, the development of proper ligands
systems that can stabilize Cu(I) metal will contribute to the
coordination chemistry and applications of this metal. The salt
metathesis reaction of CuI with two sodiumprecursors (NaBb and
NaBb-1) of bipodal scorpionate type ligands [Bb = dihydrobis(2-
mercapto-benzimidazolyl)borate, (Bb-1 = dihydrobis(2-mercapto-
benzothiazolyl)borate], has been explored in the presence of
selected phosphine ligands (PPh3, PCy3, PPh2Me, PPh2Py),
Figure 1. All of the resulting Cu(I) complexes were formed as
predominantly a singlemonomeric isomer andwere characterized
using a combination of 1H, 13C{1H}, 31P{1H} NMR spectroscopy,
and in two cases by X-ray crystallography. In the X-ray crystal
structure of complex 1 and 6, the Cu(I) center adopts a distorted
tetrahedral geometry. The complexes 1 and 6 exhibit a (B)H⋯Cu
distances of 2.008 Å and 1.866 Å length, respectively. Based on
IR spectroscopy and X-ray crystallography data, 1 and 6 adopt a
k3-S,S,H coordination mode in solid state.
