Synthesis and crystal structure of two dimeric cadmium(II) complexes bonded with pseudohalides, 1.1 and 1.3 bonding

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 mu bridges [CdL(SCN)(2)](2). The other dinuclear complex was also seen to form with cyanate ions but with the mu-bridge in a 1.1 position [CdL(OCN)(2)]. All Cd atoms are located in a distorted octahedral environment in I and 2 complexes. The Cd...Cda distances are 6.032(4) Angstrom in 1 and 3.704(3) Angstrom in 2, respectively. The N-C-S and O-C-N angles are approximately linear as 178.1(3) and 178.6(3)degrees in 1 and 177.2(5) and 176.9(7)degrees in 2, respectively. The Cd-(mu(N,S)-NCS)(2)-Cda bonds form a zig-zag structure in I and the Cd- (mu(O,N)-OCN)(2)-Cda bonds form a distorted square planar in 2.
