“…This idea was successfully explored (Bonati, Minghetti & Banditelli, 1974) and several complexes of the general formula [Au(~-3,5-R2pz)]3 were prepared (Banditelli, Bandini, Minghetti & Bonati, 1981;Banditelli, Bandini, Bonati, Goel & Minghetti, 1982). In the case of R = CF3, a crystallographic study confirmed the expected trimeric structure (Bovio, Bonati & Banditelli, 1984). Our work, which aimed at the expansion of the studies of the Italian group into other late transition-metal pyrazolato complexes, has resulted in the structural characterization of the homologous series [M(/z-3,5-Ph2pz)]3, M = Cu x, Ag I, Au i , as well as the characterization of a mixed-valence complex [Au(/z-3,5-Phzpz)]3C12 .…”

“…These kinds of ligands have a proven ability to hold metal atoms in close proximity while permitting a wide range of intermetallic separations, being useful in the synthesis of shape-persistent macrocycles, such as the homonuclear [M I A C H T U N G T R E N N U N G (m-Rpz)] 3 (M = Cu, [36][37][38][39][40][41][42] Ag, [37,38,43,44] Au; [43,[45][46][47][48][49][50] Rpz = pyrazolate or substituted pyrazolate) or [M II 3 A C H T U N G T R E N N U N G (m-Rpz) 6 ] (M II = Pd [51,52] Pt [52,53] ) as the heteronuclear clusters [Pd 2 M 2 A C H T U N G T R E N N U N G (m-Rpz) 6 ] (M = Cu, Ag, Au), [52,54] and [M 2 M' 4 A C H T U N G T R E N N U N G (m-Rpz) 8 ] (M = Pd, Pt; M' = Cu, Ag). [52,55] Apart from the interest arising from their structural diversity, some of these pyrazolate bridging complexes have also been shown to be excellent systems for examining metallophilic interactions [49,[56][57][58][59][60][61][62] and as luminescent materials.…”

This work describes the synthesis of cis-[Pt(C[triple bond]CPh)2(Hdmpz)2] (1) and its use as a precursor for the preparation of homo- and heteropolynuclear complexes. Double deprotonation of compound 1 with readily available M(I) (M = Cu, Ag, Au) or M(II) (M = Pd, Pt) species affords the discrete hexanuclear clusters [{PtM2(mu-C[triple bond]CPh)2(mu-dmpz)(2)}(2)] [M = Cu (2), Ag (3), Au (4)], in which both "Pt(C[triple bond]CPh)2(dmpz)(2)" fragments are connected by four d(10) metal centers, and are stabilized by alkynyl and dimethylpyrazolate bridging ligands, or the trinuclear complexes [Pt(mu-C[triple bond]CPh)2(mu-dmpz)(2){M(C/\P)}2] (M = Pd (5), Pt (6); C/\P = CH(2)-C(6)H(4)-P(o-tolyl)2-kappaC,P), respectively. The X-ray structures of complexes 1-4 and 6 are reported. The X-ray structure of the platinum-copper derivative 2 shows that all copper centers exhibit similar local geometry being linearly coordinated to a nitrogen atom and eta(2) to one alkynyl fragment. However in the related platinum-silver (3) and platinum-gold (4) derivatives the silver and gold atoms present three different coordination environments. The complexes have been studied by absorption and emission spectroscopy. The hexanuclear complexes exhibit bright luminescence in the solid state and in fluid solution (except 4 in the solid state at 298 K). Dual long-lived emission is observed, being clearly resolved in low-temperature rigid media. The low-energy emission is ascribed to MLM'CT Pt(d)/pi(C[triple bond]CPh)-->Pt(p(z))/M'(sp)/pi*(C[triple bond]CPh) modified by metal-metal interactions whereas the high-energy emission is tentatively attributed to an emissive state derived from dimethylpyrazolate-to-metal (d(10)) LM'CT transitions pi(dmpz)-->M'(d(10)).

“…The central nine-membered ring structure, Cu3N6, is qualitatively planar and the rings are arranged in pairs in the crystal lattice. The structure is discussed in relation to similar M(1) pyrazolate species (M = Cu, Ag, or Au) (2)(3)(4).…”

A moderately high-yield, high temperature synthesis of the title compound is reported. Crystals of tris [(3,5-dimethylpyrazolato-N',~2)copper(~)] are triclinic, a = 12.360(4), b = 14.637(4), c = 12.358(4) A, a = 105.29(2), P = 119.83(2), y = 93.99(3)", Z = 4 (trimers, two per asymmetric unit), space group P i . The structure was solved by heavy atom methods and was refined by full-matrix least-squares procedures to R = 0.034 andR,, = 0.038 for 3877 reflections with1 2 3a(4. The structure consists of trimeric molecules with an unusually short average Cu-N distance of 1. et Z = 4 (deux trimbes par unite asymktrique). On a affint la structure par la mtthode des atomes lourds et on l'a affinee par la mtthode des moindres canes jusqu'a des valeurs respectives de R = 0,034 et R,, = 0,038 pour 3877 reflexions avec I 3 o Q . La structure est formte de molCcules trimtres dans lesquelles la distance moyenne Cu-N, 1,852 A, est anormalement courte. Les cycles centraux a neuf chafnons de Cu3N6 sont plans a moins de 0,07 A. Des interactions Cu...Cu faibles, de distance moyenne 2,946 A, retiennent les unites de trimere par paires autour de centres de symttrie.Mots clks : trimere pyrazolato-cuivre (I), pyrazolat de cuivre (I).[Traduit par la revue]
