Complexes with free donor atoms, as potential metalloligands, are important building blocks in crystal engineering of coordination polymers and metal organic frameworks. In this work, the possibility of formation of cobalt(II) complexes with free N-donor atoms based on acetone isonicotinoyl hydrazone (Hisn), is verified. Syntheses, X-ray crystal structures and spectroscopic properties of two new cobalt(II)...
Complexation of copper(II) with a series of hetero-donor chelating Schiff bases (HLL R ) of para-substituted benzhydrazides (with R=OH, NO 2 , CH 3 O, Cl and tert-butyl substituents) and acetone affords mononuclear [Cu(LL R ) 2 ] molecules: 1 [Cu(anbhz) 2 ] (R=NO 2 ); 2 [Cu(ahbhz) 2 ] (R=OH) 3 [Cu(ambhz) 2 ] (R=CH 3 O);...
