Novel binuclear and polymeric diorganotin (IV) complexes with N-nicotinyl phosphoramides: Synthesis, characterization, structural studies and anticancer activity

Two new diorganotin complexes with formula {SnCl2(CH3)2L1}2 (C1), L1 = N-nicotinyl, N′,N″-bis(diethylamine) phosphoric triamide and {SnCl2(CH3)2L2}n (C2), L2 = N-nicotinyl, N′,N″-bis(cyclopentylamine) phosphoric triamide were synthesized and characterized by IR and NMR spectroscopy, and elemental analysis. Single crystal X-ray diffraction structural analyses confirmed all-trans and cis–trans configurations for distorted octahedral geometry in C1...
