Tricoordinate Coinage Metal Complexes with a Redox‐Active Tris‐(Ferrocenyl)triazine Backbone Feature Triazine–Metal Interactions

“…[28] In order to understand whether this behaviour is connected to the triflate anion-copper(I) is known to bind triflates in the solid state [29] -two different Cu I complexes containing tetrafluoroborate 1CuBF 4 and tetrakis{3,5-bis(trifluoromethyl)phenyl}borate (BAr F 4 À )a nions 1CuBAr F 4 were prepared and characterised, including their molecular structures in the solid state;n os ignificant changes in the cation structuralp arameters were observed( see Supporting Information). The VT NMR spectra of 1CuBF 4 and 1CuBAr F 4 in CD 2 Cl 2 match those of 1Cu very closely,a nd no peak splitting or broadening is observed for both the 11 Ba nd 19 FNMR signals at low temperatures,s uggesting no anion involvement in the equilibrium between 1Cu cl and 1Cu op in CD 2 Cl 2 .M ost likely and also observable in ah ypothetical structure for 1Cu op obtained from aD FT calculation (see Supporting Information), coordination of Cu I by the C 3 N 3 core [30] is presenti nt he open form 1Cu op .Abidentate form has also been proposed as the intermediate for the helical interconversion in ad issociativep athway by Bourissou and coworkers. [12] UV/Vis spectroscopy supports this notion;s ince the transition centred at 500 nm is mainly of d(Fe)-p*(C 3 N 3 )c haracter (cf.…”

Solar energy conversion using first row d-block metal coordination compound sensitizers and redox mediators

“…However, low fill-factors contributed to low PCEs for all devices. 233 In contrast to this co-sensitization approach, Robertson and coworkers designed a dimetallic complex 63 ( Scheme 23 ) in which the Ru( ii ) centre is in an environment similar to that in N3 or N719, and the Cu( ii ) centre is in a cyclam cavity. The absorption range and molar extinction coefficients of the dye were enhanced relative to those of N719.…”

“…[183-186,215a] In presence of ZnCl 2 , the BPT ligand undergone hydrolysis as indicated by the formation of [Zn(pz) 2 Cl 2 ] complex. [186] The same research group reported the Cu(II)mediated hydrolysis of the BPT ligand [215b] followed by complexation giving the followed by complexation Giri et al [134] [Ru(dmdptz)(phen)Cl](ClO Wu et al [136] [ Safin et al [143] [Cd( Frost et al [147] [Cd 2 (TpymT)( Safin et al [148] [Pb 2 (TPymT)(NO Wang et al [176] [ Soliman et al [185] [Cd(BPT) Carranza et al [169] [Ag(bdpdt) Berdiell et al [182] [ [Cu(TPTZ) 2 ](PF 6 ) 2 Breast cancer (MCF-7) Abdi et al [51] [Cu(TPTZ)(Ph 3 P) 2 ](PF 6 ) Cosensitized solar cells Báez-Castro et al [52,53] (Continues)…”

“…Based on S C H E M E 7 Synthesis of heterobimetallic complexes 19-22 these facts, José J. Campos-Gaxiola from Universidad Aut onoma de Sinaloa designed and synthesized a new five coordinated Cu(I)-TPTZ complexes having promising photophysical properties. The copper complex 10 was reported and fully characterized by different sets of spectrophotometric analyses (FTIR, ESI-TOF + , and NMR) and single crystal X-ray diffraction technique [52,53] (Scheme 3).…”

“…The Cu-N (triazine) and Cu-N (pyridine) distances are 2.153(2) and 2.115(2) Ǻ, respectively. [52] The third Cu-N bond with the pyridine arm is too long (3.050(2)Ǻ) to be a bond. Similar coordination behavior was found in the [Cu(TPTZ) (PPh 3 ) 2 ]NO 3 analogue.…”
