RELATIONSHIP C342V=1437.7(3)Å 3 ; Z=2 for (2).The copper(II) ions present a square base pyramidal geometry in these reported complexes with a Cu-Cu distance of 5.013and 5.017 Å for (1) and ( 2) respectively.Both compounds present antiferromagnetic behaviour with Tm of 15.5 and 32 K for (1) and (2).The magnetic behaviour will be compared with other reported Cu-VPO systems.
The synthesis, X-ray and electronic structures of electroconducting radical ion salts based on organic donors (BETS and EDX-DMTTF (X=O, Se)) with inorganic counter-ions having photochromic properties are reported.
