A chiral decorated metal-isonicotinate coordination polymer

The isostructural coordination polymers, M(isonicotinate)(tyrosinate) (H2O)2[M = Co or Ni] have been synthesized by microwave-assisted hydrothermal methods. These compounds crystallize in the non-centric space group P21. At 290 K, for the cobalt analogue the unit cell parameters are a = 6.0658(6), b...
