Heterometallic complexes and clusters with 2-boratanaphthalene ligands †

Synthesis of functional heterometallic complexes and clusters containing molybdenum and palladium or platinum, their self-assembly on gold surfaces and X-ray photoelectron spectroscopic studies

“…The Pde Mo distances are almost equal (PdeMo 2.860(2) Å and Pd 0 eMo 2.806(2) Å ) and longer than the PdePd 0 distance (PdePd 0 2.598(2) Å ). These distances, and other bonding parameters, are similar to those observed in analogous Mo 2 Pd 2 clusters and are therefore not discussed further[57,66,67].…”

The 9‐Borataphenanthrene Anion

“…[10,11, Thec orresponding complexes and related compounds have been applied in fields that span olefin polymerization catalysis, [14, 30-32, 48, 54] asymmetric synthesis, [55][56][57] and single-ion magnets. [51] Research has primarily focused on monocyclic systems,w ith three types of polycyclic boratabenzene-containing frameworks reported to date:1 -boratanaphthalenes, [58] 2-boratanaphthalenes, [29,38,59] and 9-borataanthracenes [33,[60][61][62] (A-C, Figure 2). Analogues of phenanthrene with ab oron atom at the 9-position are ap articularly interesting target since they contain adistinct B = Cmoiety at the 9-and 10-positions that may be capable of acting as aborataalkene in contrast to the fused polycyclic boratabenzenes that are currently known.…”

Gold–Heterometal Interactions and Bonds

“…Heterometallic compounds with an unsupported Au-metal bond are common for molybdenum derivatives [120][121][122][123][124] and recent examples are complexes related to the chromium derivative 129, that is (Ph 3 P)AuMo (CO) 3 (h 5 [141]. Both neutral and ionic cluster compounds containing m 3 -p-tolylmethylidyne or m 3 -ethylidyne groups bridging a trimetallic core with at least one gold atom are well represented in the chemistry of Au-W compounds [126,131,135,136,145,146].…”
