“…The structures of several copper(I1) compounds with this ligand (L'H) has been determined (13)(14)(15) bidentate forming a chelate with the metal. Platinum is a soft metal, and is not expected to form strong Pt-0 bonds with alcohols or other neutral oxygen ligands as do most first row transition metals.…”

Can. J. Chem. 62, 2657 (1984. Three types of complexes, trans-[Pt(LH),Cl,], [Pt(L),I, and [Pt(LH),(SR),I where LH = NH2-C(CH3)2(CH20H) and NH2--C(CH20H)3 and L are the deprotonated ligands, have been synthesized.The crystal structure of ~~~~S-[P~(NH,-C(CH~)~CH~OH)~C~~] has been determined by X-ray diffraction methods. The crystals are monoclinic, space group P2!/c, with a = 6,282(3), b = 20,901(13), c = 10,769(10) A, f3 = 92,64(6)", and Z = 4. The structure was refined by full-matrix least-squares analysis to a conventional R factor of 0.049 and R,, = 0.042. The coordination around the platinum atom is square planar. The Pt-C1 distances are 2.306(2) and 2.309(3) A and the Pt-N bonds are 2.060(8) and 2.07 l(7) A. The hydroxyl oxygen atoms are disordered; the disorder is different for each organic ligand.The structure is stabilized by an extensive hydrogen bonding system. We have modified these methods to prepare trans-[Pt(LH),- C12] add [Pt(L),] . Compounds of NH2-C(CH3),CH20H (identified below as L'H) were also synthesized. Organic sulphur compounds R-SH (thiophenol and thiouracil) can react with [Pt(L),] or [Pt(L1),] to form [Pt(LH),(SR),] (or L'H). The three types of complexes [Pt(LH),Cl,], [Pt(L),], and [Pt(LH),(SR),] (or L'H) are believed to be trans-isomers.In order to confirm these hypotheses, we wanted to determine the crystal structures of one compound of each type. Unfortunately, up to now, only [Pt(L1H),Cl2] gave suitable crystals for X-ray diffraction. Its crystal structure is reported below. Experimental[Pt(L2)l and lPt(L1),l K,PtC14 and LH or L'H were dissolved in water in a ratio of LH : Pt > 5. The mixture was heated to 50-70°C for about 1 h and then cooled to room temperature. The light yellow precipitate was filtered, washed with water, and dried with a vacuum pump overnight. The compounds crystallized with one (L) and two (L') molecules of water (Table 1). Yield: 80%.crystals slowly formed and they were washed with water and dried under vacuum overnight. Yield: 90%.[Pt(LH), ( A set of precession photographs showed that the crystals belong to the P 2 , l c space group. The cell parameters were calculated by least-squares refinement from the setting angles of 15 centered reflections on a Syntex P1 diffractometer using graphite-monochromatized MoKa radiation. A total of 4140 independent reflections were measured with 28 < 60" by the 8-28 scan technique using MoKa radiation. The scan rate was l o (28) min-' for most reflections, but rates as high as 24" min-I were selected for strong reflections by the autocollection program. A 28 scan range of lo below Ka, and lo above Ka, was chosen. The background time to scan time ratio was 0.50. Reflections with I,,, < Crystal data

“…Owing to the large number of derivatives, commercial availability, and potential for multiple coordination modes, we became interested in expanding the scope of these alkanolamine ligands with copper(II) formate, with the aim of isolating discrete complexes whose structure-reactivity relationship could be probed. 4-coordinate square planar complexes were synthesized by Bertrand and Muhonen [34,35] in the early 1980s from a hydrated copper source, but there is much scope for expansion both in terms of coordination number and ligand type. Herein, we explore the coordination of a series of alkanolamine ligands with copper(II) formate and for the first time, employ computational analysis to aid our understanding of the structural and observed decomposition profiles of the isolated complexes.…”

“…When a 1:1 stoichiometry was used, no reaction occurred whilst 1:3 and greater would yield the previously reported CuL 2 compound.

Bridging between Cu atoms occurs through the oxygen atoms of the alkanolamine such that each Cu is 4-coordinate.…”

Unraveling the Steric Link to Copper Precursor Decomposition: A Multi‐Faceted Study for the Printing of Flexible Electronics

The field of printed electronics strives for lower processing temperatures to move toward flexible substrates that have vast potential: from wearable medical devices to animal tagging. Typically, ink formulations are optimized using mass screening and elimination of failures; as such, there are no comprehensive studies on the fundamental chemistry at play. Herein, findings which describe the steric link to decomposition profile: combining density functional theory, crystallography, thermal decomposition, mass spectrometry, and inkjet printing, are reported. Through the reaction of copper(II) formate with excess alkanolamines of varying steric bulk, tris-co-ordinated copper precursor ions: "[CuL 3 ]," each with a formate counter-ion (1-3) are isolated and their thermal decomposition mass spectrometry profiles are collected to assess their suitability for use in inks (I 1-3 ). Spin coating and inkjet printing of I 1,2 provides an easily up-scalable method toward the deposition of highly conductive copper device interconnects (𝝆 = 4.7-5.3 × 10 −7 𝛀 m; ≈30% bulk) onto paper and polyimide substrates and forms functioning circuits that can power light-emitting diodes. The connection among ligand bulk, coordination number, and improved decomposition profile supports fundamental understanding which will direct future design.
