modification 6b has a more complicated crystal structure, which is composed of both monomeric complex units such as those found in 6a and infinite chains of coordination polymers. The copper atoms in the polymeric chains of 6b display fivefold coordination and a ligand polyhedron that is an intermediate form between a trigonal-bipyramidal and a square-pyramidal geometry.

the crude product 2b with aqueous sodium carbonate solution led to the formation of the dinuclear carbonato-bridged complex [(11-Me-BPI)Pd}2(μ-CO3)] (3) which was characterized by an X-ray structure analysis. Reaction of 11-Br-BPI (1c) with a large excess (6 equiv.) of the acetylenes Me3SiCCH, Ph3SiCCH and PhCCH under Sonogashira conditions gave the alkynylated derivatives 11-(Me3SiCC)-BPI (4a), 11-(Ph3SiCC)-BPI

2-aminopyridine derivatives gave the corresponding BPIligands. Reaction of the ethyleneglycol functionalizedBPI derivative with the zeroth generation carbosilane dendrimer [G-0]4- exo -Cl yielded the functionalized dendrimer [G-0]4- exo -[O(CH2)2O]-10- MeBPI ( 7 ). The synthesis of the palladium complexes was carried out by reaction of the protioligands with [( Ph CN)2PdCl2] in benzene using triethylamine as
