Group 11 metals form with pyrazolate ligand complexes a general formula of [MPz]n. The value “n” varies depending on the type substituent in and metal atom. Copper(I) silver(I) ions mainly cyclic di-, tri-, tetra-nuclear or polymeric structures. Cyclic trinuclear d10 pyrazolates [MPzm]3 (M = Cu(I) Ag(I); Pz substituted ligand) are particular interest because their planar structure allows them to supramolecular aggregates via noncovalent metal–metal, metal–π, metal–electron donor...

The contact printing method is widely used to create microchips and develop highly sensitive biosensors. This based on techniques for immobilizing biomolecules. In this work, two effective methods covalent immobilization of oligonucleotides, the reactions disulfi de bond formation azide-alkyne cycloaddition, were optimized method. With both strategies, oligonucleotides retain ability hybridize with complementary DNA, which provides basis their practical use in bioanalytical applications.
The first example of trinuclear copper(I) and silver(I) pyrazolates adducts with a tertiary diphosphine (Ph2PCH2PPh2) retaining trimeric [MPz]3 core is reported.

Abstract Herein, we describe an approach to cage metallasilsesquioxanes by self‐assembly with 1,2‐bis(diphenylphosphino)ethane as a key reactant. This allowed us achieve unique family of complexes that includes anionic tetra‐ and nonanuclear copper(II) sodium silsesquioxane cationic copper(I) components. Additional representatives this intriguing metallasilsesquioxane (Cu 9 Na 6 Cu 3 Cs ) were obtained through the replacement original ethanol‐based reaction medium DMSO. The fascinating...
