Reaction between 2-hydroxy-1-naphthaldehyde thiosemicarbazone and square planar dichloro bis triphenylphosphine Cu(II) resulted in two structurally different binuclear Cu(I) tetrahedral complexes which are co-crystallized together by exhibiting bonding isomerism. The reaction of co-crystallized complexes with [NiCl2(PPh3)2] led to C–S and Cu–S activation of coordinated ligand to form [Cu2(μ2-Cl2)(PPh3)3] and [Cu2(μ2-S2)(PPh3)3] respectively along with a square planar [Ni(nap-tsc)(PPh3)] (where, nap-tsc =2-hydroxy-1-naphthaldehyde thiosemicarbazone) and triphenylphosphine sulfide.
