摘要：

As a continuation of the study on using the tetrazolate ligands to construct coordination polymers, two isomorphous 3D coordination polymers built on Delta-chain topological rod-shaped SBUs have been synthesized with formulae [M-2(mu(3)-OH)(LL2)-L-1](n) (5-amino-1H-tetrazole (HL1), 2,3-pyrazinedicarboxylic acid (H2L2) and different 3d spin carriers (M = Mn-II, 1 and Co-II, 2)). The SBU consists of corner-sharing [M-3(mu(3)-OH)] isosceles triangle motifs with mixed multiple (mu(4)-tetrazolyl, mu(3)-OH, syn-syn carboxylate) bridges. The SBUs were further linked by syn-anti carboxylates to form the sra net. Spin-competing was observed in the Mn-II compound, whereas the Co-II compound exhibits spin-canting.
