Load table with json using Datatables

I'm using the jquery Datatables version 1.10.7 plugin.

I'm trying to load a table following the following structure:

JSON

{
    "d:" [
        {   "IdNotificacao":null,
            "Contrato":{
                "id":631,
                "serie":2210618,
                "dataAdesao":"29/04/2015",
                "diaVencimento":16,
                "contribuicaoMensal":0.9259
            },
            "PagamentoDoContrato":[{
                "$id":"6",
                "id":16072,
                "idContrato":631,
                "parcela":1,
                "valorBruto":328.70,
                "valorLiquido":323.77,
                "dataPagamento":"30/04/2015"                
            }],
            "Assembleia":{"$ref":"3"},
            "GrupoCota":{"$ref":"2"},
            "Cliente":{
                "$id":"9",
                "id":631,
                "cpf_cnpj":"1xx3xx1xx7x",
                "nome":"JESSICA ABDC",
                "renda":2500.00
            },          
            "TipoDaNotificacao":null,
            "CanalDeEnvio":"SMS",
            "DataEnvio":"10/06/2015 14:24:33",
            "DataRecebimento":"10/06/2015 14:25:21",
            "DataLeitura":"",
            "Recebida":"Recebida",
            "Lida":"Não Lida",
            "ObservacaoRecebimento":"",
            "ObservacaoLeitura":"",
            "DestinatarioEnvio":"319xx88xx6"
        }
    ]
}

** Json is received via Ajax *.

When you do not have list list in json, I do it as follows:

function(data) {
  var Dados = eval(data.d);
  
  $('#table_vencimento').dataTable({
    "bJQueryUI": true,
    "bLengthChange": false,
    "iDisplayLength": 10,
    "oLanguage": {
      "sUrl": "pt.txt"
    },
    data: Dados,
    columns: [{
      data: 'Cota'
    }, {
      data: 'CpfCliente'
    }, {
      data: 'NomeCliente'
    }, {
      data: 'DestinatarioEnvio'
    }, {
      data: 'DataEnvio'
    }, {
      data: 'Recebida'
    }, {
      data: 'DataRecebimento'
    }, {
      data: 'ObservacaoRecebimento'
    }, {
      data: 'Lida'
    }, {
      data: 'DataLeitura'
    }, {
      data: 'ObservacaoLeitura'
    }, {
      data: 'CanalDeEnvio'
    }, ]
  });
}

JSON

    {
    "d:" [
        {   "IdNotificacao":null,
            "TipoDaNotificacao":null,
            "CanalDeEnvio":"SMS",
            "DataEnvio":"10/06/2015 14:24:33",
            "DataRecebimento":"10/06/2015 14:25:21",
            "DataLeitura":"",
            "Recebida":"Recebida",
            "Lida":"Não Lida",
            "ObservacaoRecebimento":"",
            "ObservacaoLeitura":"",
            "DestinatarioEnvio":"319xx88xx6"
        }
    ]
}

This is a "no list" JSON.

MY PROBLEM

I'm not able to properly load a table using datatables , when JSON has several levels (or list list), as exemplified above.
