Synthesis, X-ray Structure and Hirshfeld Surface Analysis of Zn(II) and Cd(II) Complexes with s-Triazine Hydrazone Ligand

The two group IIB complexes [Cd(DMPT)Cl2] (6) and [Zn(DMPT)Cl2] (7) of the tridentate ligand (DMPT), 2,4-bis(morpholin-4-yl)-6-[(E)-2-[1-(pyridin-2-yl) ethylidene]hydrazin-1-yl]-1,3,5-triazine were synthesized, their structural aspects elucidated with aid X-ray crystallography. Both crystallized in monoclinic crystal system, P21/n as a space group. unit cell parameters for 6 are = 14.1563(9) Å, b 9.4389(6) c 16.5381(11) Å β 91.589(5)° while respective values 7 11.3735(14), 13.8707(13), 14.9956(16), 111.646(2)°. volume is slightly less (2198.9(4) Å3) complex compared to (2209.0(2) Å3). have penta-coordination environment around metal ion, where DMPT acts neutral NNN-chelate via pyridine, hydrazone, one s-triazine N-atoms. Cd(II) close square pyramidal configuration some distortion. On other hand, ZnN3Cl2 coordination highly distorted located intermediately between trigonal bipyramidal pyramids. Supramolecular structure analysis Hirshfeld calculations indicated importance Cl…H, O…H, C…H interactions. Their percentages calculated be 20.9, 9.1, 8.7%, respectively. For 7, C…H, N…H contacts most important. 20.3, 9.0, 7.0, 8.4%, In both complexes, major intermolecular interaction hydrogen–hydrogen interactions which contributed 45.5 46.6%,
