Reactivity of phosphido-bridged diplatinum complexes towards electrophiles: synthesis of new hydrides and related Pt2Cu and Pt2Ag clustersDedicated to Prof. D. Fenske on the occasion of his 60th birthday, with our most sincere congratulations and best wishes.

An organometallic tetranuclear cluster with phosphine and phosphido ligands in nonclassical bonding modes: X-ray structural characterization

“…The interaction between the phosphido containing P(2) and the Pd(2) centre is very noteworthy and different to the previously proposed interaction. The Pd(2)-C(37) distance (2.391(5) Å ) is rather short [18][19][20][21][22][23][24][25], as is the Pd(2)-P(2) distance (2.272(1) Å ), in fact it is even Scheme 1. shorter than the Pd(1)-P(2) and Pt(1)-P(2) distances (2.389(1) and 2.358(1) Å , respectively). These data indicate that the P(2)-C(37) bond interacts with the Pd(2) centre giving rise to a 2e-3c bond or an agostic-like interaction of a P-C sp2 bond with an unsaturated metal atom, as it has been recently called for related phosphine complexes [26][27][28].…”

Gold Phosphide Complexes

“…Thus, the chemistry of phosphido-bridged derivatives of the main group elements [1][2][3] or transition metals [4][5][6] has been a matter of interest for various research groups in the last few years. While there are many phosphido complexes with metals, mainly of groups 6 7-12 or 10, [13][14][15][16][17][18][19][20] the chemistry of gold derivatives has experienced less progress in this field of research in spite of the possible catalytic behaviour of di-and polynuclear phosphido-bridged compounds. 21 This is an interesting field of research, because the substitution of one or more protons by metal atoms allows the synthesis of homo-or heteropolynuclear compounds in which the presence of a small bridging atom, such as phosphorus, may give rise to intermetallic contacts, which, as is known, are often responsible for surprising and interesting optical properties, such as luminescence, area with an increasing importance in the last years.…”

Quantum chemistry studies on the Ru–M interactions and the 31P NMR in [Ru(CO)3(Ph2Ppy)2(MCl2)] (M=Zn, Cd, Hg)

“…The interaction energies DE H between [Ru(CO) 3 (Ph 2 PH) 2 ] and MCl 2 fragments were then calculated according to Eq. (1) and are showed in Table 3 Table 4.…”

“…Over the past two decades, heterometallic complexes containing metal-metal bond have been extensively studied due to their unique structures and properties including catalysis [1][2][3][4][5][6] and spectroscopy [2,5,[7][8][9]. Much interest is focused on the study of polydentate ligands with maingroup donors that are able to form various polynuclear complexes, such as 2-(diphenylphosphino)pyridine (Ph 2 -Ppy) [2,3,5], 2,6-bis(diphenylphosphino)pyridine [2,5], bis(dimethylphosphino)methane(dmpm) [10], bis(diphenylphosphino)methane(dppm) [2,4].…”
