abstract
In this work we have reported two new Cd(II) complexes viz. [Cd-2(L)(2)(NO3)(2)] (1) and [Cd-2(L)(2)(NCS)(2)] (2) where HL = (E)-2-methoxy-6-((quinolin-8-ylimino) methyl) phenol. Both of the complexes have been characterized using different spectroscopic techniques along with single crystal X-ray crystallography. Complexes 1 and 2 are di-(phenoxido)-bridged Cd(II) complexes where NO3- and NCS- act as terminal coligand. Complexes 1 and 2 feature uncommon distorted monocapped trigonal prismatic geometry and distorted octahedral geometry around Cd(II) centre, respectively. Different non covalent interactions are present in the crystal packing of complexes 1 and 2. Complex 2 reveals chalcogen bonding and unconventional pi-pi interactions. The energetic features of such type of interactions have been studied by means of DFT calculations and characterized energetically using the NBO computational tool. (C) 2017 Elsevier B.V.
