trans-Bis(4,7-diphenyl-1,10-phenanthroline-κ²N,N′)bis(nitrato-κ²O,O′)zinc(II)

Abstract

The title compound, [Zn(NO3)2(C24H16N2)2], is a twofold axially symmetric coordination compound. Given that the Zn—O interactions [2.4926 (15) and 2.6673 (15) Å] can be considered as weakly bonding and the nitrate ions share the same C 2 axis of the Zn(dpp)2 fragment (dpp is 4,7-diphenyl-1,10-phenanthroline), these anions belong to the coordination sphere of Zn2+, leading to a complex with an overall coordination number of 8 for the metal ion.

Exploring the cytotoxic activity of new phenanthroline salicylaldimine Zn(II) complexes

“…The Zn-N Bphen bond lengths, ranging from 2.135(2) to 2.157(2) Å, are in agreement with those found in the literature for this type of bonds [62][63][64]. A monomeric cationic Zn(II)-complex containing two phen molecules and a bidentate acetate showed similar Zn-N bond lengths (2.133 to 2.140 Å) [65].…”
