Abstract The reactions of the N‐heterocyclic carbene‐parent phosphinidene adducts (IMes)PH ( 1 a ) and (IDipp)PH b with one equivalent copper(I) or silver(I) chloride afforded monometallic complexes [{(IMes)PH}MCl] 2 , M=Cu; M=Ag) [{(IDipp)PH}MCl] 3 M=Ag). Single‐crystal X‐ray diffraction analyis provided evidence for higher tendency ligand to form polynuclear structures bridging NHC‐phosphinid...

A series of cyclometalated iridium(III) complexes with 2-phenylquinoline ligand (1-4) were designed and synthesized, which were thoroughly investigated by the photophysics, electrochemistry, theoretical calculations and electrochemiluminescence (ECL). By incorporating methyl groups into the 2-phenylquinoline, the corresponding complexes 2 and 3 displayed lower oxidative potential and higher HOM...

The ligation of a N-heterocyclic carbene (NHC) to group 11 metal salts (Cu, Ag) was explored as an alternative to PR(3) ligands for the formation of copper- and silver-chalcogenolate cluster complexes. AgOAc and CuCl salts ligate with the NHC 1,3-di-isopropylbenzimidazole-2-ylidene ((i)Pr(2)-bimy) forming [Ag(OAc)((i)Pr(2)-bimy)] 1, [Ag(OAc)((i)Pr(2)-bimy)(2)] 2, [CuCl((i)Pr(2)-bimy)](2)3 and [...

In the title compound, {[Cu(C(7)H(4)NO(4))(C(10)H(8)N(2))(H(2)O)]·H(2)O}(n), the Cu(I) ion is coordinated by the N atom from a 5-carb-oxy-pyridine-3-carboxyl-ate anion, two N atoms from two 4,4'-bipyridine (4,4'-bipy) ligands and one water mol-ecule in a distorted tetra-hedral geometry. The 4,4'-bipy ligands bridge the Cu(I) ions into polymeric chains propagating in [201]. The latticeand the co...

In the title compound, [Ag(C(8)H(5)O(7)S)(C(10)H(8)N(2))](n), the Ag atom is tetra-coordinated by two 4,4'-bipydidine (4,4'-bipy) N atoms and two monodentate sulfonate O atoms of the 5-sulfoisophthalic acid (H(3)sip) ligands. Adjacent Ag atoms are bonded through four sulfonate O atoms, forming a dinuclear unit with an Ag⋯Ag separation of 3.384 (5) Å; they are further linked together by the 4,4'...

[MF(4)(dmso)(2)] (M = Zr or Hf) and [MF(4)(dmf)(2)], prepared by dissolving MF(4)·nH(2)O in the appropriate solvent, have been used as synthons for a range of complexes of these otherwise intractable tetrafluorides. These reagents react with OPR(3) (R = Me or Ph) or OAsPh(3) (L) in anhydrous CH(2)Cl(2) to form six-coordinate [MF(4)L(2)] which exist as a mixture of cis (predominant form) and tra...

The design and research of luminescent volatile organic compound (VOC) fluorescent sensing materials are great significance challenge. We report herein the ligand substitution reaction VOC new heteroleptic [Cu(P ˄ P)N 2 ] + type copper(I) complexes. Firstly, three complexes 1 – 3 were designed by utilizing a chelate diphosphine 4,5‐bis(diphenylphosphino)‐9,9‐dimethylxanthene (Xantphos) synthesi...
