Hydrothermal reaction of CoCl(2) with trans-3-pyridylacrylic acid (3-pycaH) and Et(3)N results in the formation of a new three-dimensional network formulated as [{Co(4)(mu-H(2)O)(2)(3-pyca)(8)}(0.94){Co(5)(mu(3)-OH)(2)(3-pyca)(8)}(0.06)]. Magnetic measurements reveal that spin-canting and metamagnetic behavior coexist in this compound with a critical temperature at 9.5 K.
