Silver Complexes with Nitrogen Donor Ligands-Co-ordination Number 2 and 3

Linear two-coordinated silver (I) complexes having the formula [AgL₂]ClO₄ , where L is 3-chloro, 3-bromo and 3-ethyl pyridine, 3,5-lutidine, 2- and 8-methyl quinoline are characterised. They are 1 : 1 electrolytes and contain ionic perchlorate group. Also, compounds having the formula [AgL₂.NO₃], where L is 3-chloro and 4-cyano pyridine and 3,5-lutidine have been isolated. These are non-electrolytes and infra-red spectra indicate the presence of co-ordinated nitrato groups and thus exhibit a co-ordination number 3.
