Four coordination networks of composition [CuL2(H2O)(NO3)]. NO3.H2O (1) [CdL2(H2O)(NO3)]. NO3.H2O (2) (L = NN'-bis(4-pyridylmethyl)urea), [CuL2(NO3)]. 2H(2)O . 2EtOH (3) (L = NN'-bis(3-pyridylmethyl)urea) and [CdL2(H2O)(2)]. 2NO(3) (4) (L = N,N'-bis(3-pyridylmethyl)urea) have been prepared. Structures 1, 2 and 4 consist of looped chains, structure 3 consists of a two-dimensional network. (C) 2001 Published by Elsevier Science B.V.
