“…In other words, to end up as metallic copper, the Cu(en)2(HCOO)2 complex needs to surpass an energetically unfavorable intermediate, therefore requiring a higher temperature. For the anhydrous αcopper formate (detailed MCR-ALS XANES in supporting info S12), the situation is even more pronounced: not only is its Cu(I) intermediate likely to be a square planar dimeric Cu(I) chainlike structure, as indirectly observed in literature [54] and in concordance with the well-known structure of similar Cu(I)carboxylates [55,56]. Moreover, the strong network of carboxylate bridges in the α-Cu(II)(HCOO)2 structure needs to be broken apart completely, not only to end up with the metallic Cu(0) fcc structure, but also to form the unstable Cu(I) dimers which have little in common with their parent structure.…”

The fast and scalable low-temperature deposition of nanoscale metallic features is of the utmost importance for the development of future flexible smart applications including sensors, wireless communication and wearables. Recently, a new class of metalorganic decomposition (MOD) copper inks was developed, consisting of self-reducing copper formate containing amine complexes. From these novel inks, copper metal features with outstanding electrical conductivity (± 10 μΩ cm) are deposited at temperatures of 150 °C or less, which is well below the reduction temperature of orthorhombic α-copper formate (around 225 °C). However, the underlying principle of this reaction mechanism and the relationship between the corresponding temperature shift and the amine coordination is still under debate. The current study provides a full explanation for the shift in reduction temperatures via in-situ characterization. The results clearly indicate that the structural resemblance and stability of the Cu(II) starting compound and the occurring Cu(I) intermediate during the in-situ reduction, are the two main variables that rationalize the temperature shift. As such, the thermal compatibility of the copper MOD inks with conventional plastic substrates like polyethylene terephthalate (PET) can be explained, based on the metalorganic complex properties.

“…The dimensions of the tetramer are given in (1) is also found in bis(3-hydroxy-4phenyl-2, 2, 3 -trimethylcyclohexanecarboxylato) disilver (I) dihydrate (Coggon & McPhail, 1972) with dimensions Ag...Ag 2.778(5), 2.834(5), Ag-O 2.20, 2.29 A; and in silver perfluorobutyrate (Blakeslee & Hoard, 1956) with dimensions Ag...Ag 2.90(2), Ag-O 2-25 (4) ,&. Silver glycine nitrate (Rao & Viswamitra, 1972) also contains this dinuclear unit but the units are linked by further Ag-O interactions to give a polymeric structure similar to that found in copper(I) acetate (Drew, Edwards & Richards, 1973;Mounts, Ogura & Fernando, 1974…”

“…In studies that concerned acetate carboxyl groups, a clear relationship between the m asym (COO À ) and m sym (COO À ) bands of the FTIR spectrum (region of 1350-1750 cm À1 ) and the metal-carboxylate coordination type has been reported, [24][25][26][27] with the bands corresponding to the coordinated modes situated at different frequencies relative to those for the free carboxylate ion. The frequencies of these bands are highly sensitive to the structure of the carboxylate group, the nature of the solvent, the nature of the ligand and the identity of the metal ion, 28 therefore, the separation of the bands (i.e., Dm = CO asym ÀCO sym ) is also indicative of the structure of a given carboxylate.…”
