Abstract
Two different complexes were obtained from (dmpp) and Cd(II) ions with the aid of pseudohalide ions in non-aqueous solvents. The dinuclear complex formed with thiocyanate ions shows, using XRD, to posses two 1.3 bond μ bridges [CdL(SCN)2]2- The other dinuclear complex was also seen to form with cyanate ions but with the μ-bridge in a 1.1 position [CdL(OCN)2]. All Cd atoms are located in a distorted octahedral environment in 1 and 2 complexes. The Cd... Cda distances are 6.032(4) Å in 1 and 3.704(3) Å in 2, respectively. The N-C-S and O-C-N angles are approximately linear as 178.1(3) and 178.6(3)° in 1 and 177.2(5) and 176.9(7)° in 2, respectively. The Cd-(μN,S-NCS) 2-Cda bonds form a zig-zag structure in 1 and the Cd-(μO,NOCN)2-Cda bonds form a distorted square planar in 2.
