In the title coordination polymer, {[Zn(SO4)(C18H16N6O2)(H2O)3]·CH3OH·H2O}n, the Zn2+ ion adopts a slightly distorted cis-ZnN2O4 octahedral geometry arising from three coordinated water molecules, one sulfate ion and two bridging 3,3′-bis(3-pyridyl)-1,1′-(m-phenylene)diurea (bpmpbu) ligands. The dihedral angles between the central benzene ring and two terminal pyridine rings of the bpmbpu molecule are 10.58 (17) and 34.63 (16)°. In the crystal, the ligands bridge the ZnII ions, thus generating a one-dimensional zigzag coordination polymer propagating in [010]. The features extensive N—H⋯O and O—H⋯O hydrogen-bonding interactions.

3-Aminopyridine (1 g, 10.6 mmol) and triethylamine (3 ml) were stirred under nitrogen in 150 ml of anhydrous dichloromethane in ice cold condition for 20 min. To this stirring solution, triphosgene (1.57 g, 5.3 mmol) was added and kept stirring for another 20 min at 0°C and to the resultant solution, meta-phenylenediamine (574 mg, 5.3 mmol) in 10 ml of dichloromethane was added dropwise. White precipitate was obtained after 24 hour of stirring at room temperature. The precipitate was filtered, air dried, treated with 5% NaHCO3 solution and washed with distilled water. Pale yellow coloured microcrystalline material of the BPMPBU ligand was obtained (880 mg, 55% yield) after recrystallization from H2O/MeOH (1 : 2 v/v) (880 mg, 55% yield) . mp 265-267°C Anal. data calc. for C18H16N6O2: C, 62.06; H, 4.63; N, 24.12.

Whenever possible, the hydrogen atoms were located on a difference Fourier map and refined. In other cases, the hydrogen atoms were geometrically fixed. The positional parameters of hydrogen atoms of the water molecules and methanol molecule were refined with the constraint Uiso(H) = 1.2 or 1.5Ueq(carrier) applied.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

As part of our ongoing studies of functional coordination polymers (CPs) and metal-organic frameworks (MOF) (Adarsh et al., 2008, 2009), we now report a coordination polymer derived from a newly synthesized bis-pyridyl-bis-urea ligand N,N'-bis(3-pyridyl)meta-phenylene-bis-urea (BPMPBU). Suitable single crystals of [{Zn(H2O)3(SO4)(µ-BPMPBU)}.H2O.MeOH]∞, (I), were obtained by layering an methanolic solution of BPMPBU over aqueous solution of ZnSO4 in 1:2 metal–ligand ratio (see experimental). It was crystallized in the monoclinic non centrosymmetric space group P21. In the asymmetric unit, the metal center Zn(II) is found to be hexacoordinated; while euqatorial positions are occupied by pyridyl N atoms of the ligand and water molecules, the apical positions are coordinated by O atoms of water and sulfate. The ORTEP diagram of 1 with 50% probability is given in Fig. 1. The metal center Zn(II) displayed a distorted octahedral geometry [N—Zn—N = 94.72?(12)°; O—Zn—N = 87.4)(12)-93.83 (10)°; O—Zn—O = 87.01 (11)-91.12 (12)°]. In the crystal structure, the ligand BPMPBU which displayed syn-syn-syn conformation (scheme 1) coordinated to the adjacent Zn(II) metal centres via pyridyl N atoms leading to the formation of a 1D zigzag polymeric chain (Fig. 2). The polymeric chains are further packed in parallel fashion sustained by N–H···O hydrogen bonding interactions involving sulfate and the urea moieties [N···O = 2.875 (4)–3.044 (4) Å; N–H···O =154–164°]. Both the lattice included water and MeOH are occupied within the interstitial space of the chains and are involved in O—H···O hydrogen bonding interactions [O···O = 2.633 (3)–2.942 (3) Å; O–H···O] (Fig. 3).
