Abstract: Synthesis and crystal structure packing of [(2,2'-bipy)M(SeC{O}Ph)2], where M=Zn, (1) or Cd, (2), are described. In 1, the pyridyl groups in 2,2'-bipy rings are engaged in ⋯ interactions with the neighboring pyridyl rings to form 1D polymer along c-axis. The neighboring phenyl rings also have close ⋯ contacts generating 2D supramolecular sheets in ac-planes. On the other hand, two [(2,2'-bipy)Cd(SeC{O}Ph)2] molecules form a dimer at the crystallographic inversion center through Se ⋯ Se interactions. A pair of 2,2'-bipy rings from neighboring dimers interact through ⋯ contacts and hence propagating this as a 1D supramolecular chain. The difference in the packing has been attributed difference in conformation of monomers due to coordination number and geometry.
