Coordination networks from ;N,N?-bis(3-or 4-pyridylmethyl)urea and Cu(II) or Cd(II) nitrate

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

Synthesis and characterisation of polymeric metal-ion carboxylates from benzene-1,3,5-tricarboxylic acid with Mn(II), Co(II) or Zn(II) and 2,2-bipyridyl, phenanthroline or a pyridyl-2-(1-methyl-1H-pyrazol-3-yl) derivative

A total of 13 new co-ordination solids have been prepared of composition [Co(HBTC)(PHEN)(H2O)] (12), [Mn-3(BTC)(2)(PHEN)(3)] (13), [Mn(HBTC)(6)(H2O)] (14), [Mn(HBTC)(7)(H2O)] (15), [Zn-3(BTC)(2)(6)(3)(H2O)(3)]. 4H(2)O (16), [Zn-(HBTC)(6)(H2O)] (17), [Zn(H2BTC)(2)(6)] (18), [Zn(HBTC)(7)(H2O)] (19), [Zn(HBTC)(8)(H2O)] (20), [Zn-2(HBTC)(2)(9)(2)]. 2H(2)O (21), [Zn(HBTC)(10)(H2O)].H2O (22), [Co(HBTC)(10)(H2O)].H2O (23) and [Co(HBTC)(11)(H2O)] (24) 6 = pyridine-2-(1-methyl-1H-pyrazol-3-yl); 7 = pyridine-2-(1-methyl-4-bromo-1H-pyrazol-3-yl); 8 = pyridine-2-(1-methyl-4-nitro-1H-pyrazol-3-yl); 9 = pyridine-2-(1-methyl-5-trifluoromethyl-1H-pyrazol-3-yl); 10 = pyridine-2-(1-methyl-5-tert-butyl-1H-pyrazol-3-yl); 11 = pyridine-2-(1-methyl-4-nitro-5-tert-butyl-1H-pyrazol-3-yl). Compounds 12, 14, 15 and 24 have similar structures which contain metal atoms in M2O2 rings. Compounds 17, 19 and 20 all contain single stranded coordinative chains. At low temperatures compounds 14 and 15 both have high spin S = 5 ground states
